Hi Bitcoiners! I’m back with the fifteenth monthly Bitcoin news recap. For those unfamiliar, each day I pick out the most popularelevant/interesting stories in Bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in bitcoin over the past month. And a lot has happened. It's easy to forget with so much focus on the price. Take a moment and scroll through the list below. You'll find an incredibly eventful month. You can see recaps of the previous months on Bitcoinsnippets.com A recap of Bitcoin in March 2018
LATEST UPDATE: 23 August 2018 - Commencement of Filing Proofs of Rehabilitation Claim (deadline is October 22, 2018)

Proper Care & Feeding of your CryptoLocker Infection: A rundown on what we know.
This article is no longer being maintained, please see the new version here. Thanks. tl;dr: I hope you have backups. It's legit, it really encrypts. It can jump across mapped network drives and encrypt anything with write access, and infection isn't dependent on being a local admin or UAC state. Most antiviruses do not catch it until the damage is done. The timer is real and your opportunity to pay them goes away when it lapses. You can pay them with a GreenDot MoneyPak or 2 Bitcoins, attempt to restore a previous version using ShadowExplorer, go to a backup, or be SOL. Vectors: In order of likelihood, the vectors of infection have been:
Email attachments: A commonly reported subject is Payroll Report. The attachment, most of the time, is a zip with a PDF inside, which is actually an executable.
PCs that are unwitting members of the Zeus botnet have had the virus pushed to them directly.
There is currently one report of an infection through Java, using the .jnlp file as a dropper to load the executable.
Variants: The current variant demands $300 via GreenDot MoneyPak or 2 BTC. I will not attempt to thoroughly monitor the price of bitcoins for this thread, use Mt. Gox for the current exchange rate. Currently the MoneyPak is the cheaper option, but last week Bitcoins were. Two variants, including a $100 variant and a $300 that did not offer Bitcoin, are defunct. Payload: The virus stores a public RSA 2048-bit key in the local registry, and goes to a C&C server for a private key which is never stored. The technical nuts and bolts have been covered by Fabian from Emsisoft here. It will use a mix of RSA 2048-bit and AES 256-bit encryption on files matching these masks: *.odt, *.ods, *.odp, *.odm, *.odc, *.odb, *.doc, *.docx, *.docm, *.wps, *.xls, *.xlsx, *.xlsm, *.xlsb, *.xlk, *.ppt, *.pptx, *.pptm, *.mdb, *.accdb, *.pst, *.dwg, *.dxf, *.dxg, *.wpd, *.rtf, *.wb2, *.mdf, *.dbf, *.psd, *.pdd, *.eps, *.ai, *.indd, *.cdr, ????????.jpg, ????????.jpe, img_*.jpg, *.dng, *.3fr, *.arw, *.srf, *.sr2, *.bay, *.crw, *.cr2, *.dcr, *.kdc, *.erf, *.mef, *.mrw, *.nef, *.nrw, *.orf, *.raf, *.raw, *.rwl, *.rw2, *.r3d, *.ptx, *.pef, *.srw, *.x3f, *.der, *.cer, *.crt, *.pem, *.pfx, *.p12, *.p7b, *.p7c, *.pdf, *.tif This list of file masks may be incomplete. Trust this list at your peril. When in doubt, CryptoLocker will show you what files it has encrypted by clicking the relevant link in the virus's message. It will access mapped network drives that the current user has write access to and encrypt those. It will not attack server shares, only mapped drives. Current reports are unclear as to how much permission is needed for the virus to encrypt a mapped drive, and if you have clarification or can test in a VM please notify me via message. By the time the notification pops up, it's already encrypted everything. It's silent until the job is done. Many antiviruses have been reported as not catching the virus until it's too late, including MSE, Trend Micro WFBS, Eset, GFI Vipre, and Kaspersky. They can further complicate matters by reverting registry changes and removing the executables, leaving the files behind without a public or private key. Releasing the files from quarantine does work, as does releasing the registry keys added and downloading another sample of the virus. Windows XP through 8 have all reported infections. What's notable about this virus, and this is going to lead to a lot of tough decisions, is that paying them to decrypt the files actually does work, so long as their C&C server is up. They verify the money transfer manually and then push a notification for the infected machine to call home for the private key again, which it uses to decrypt. It takes a long time to decrypt, at the rate of roughly 5GB/hr based on forum reports. The virus uses the registry to maintain a list of files and paths, so not moving the files around is vital to decryption if you are paying them. Also notable is that the timer it gives you to pay them does appear to be legitimate, as multiple users have reported that once the timer ran out, the program uninstalled itself. Reinfecting the machine does not bring a new timer. I was not able to verify the uninstallation of the program after the timer ran out, it appears to be dependent on internet access. Due to the nature of the encryption, brute-forcing a decrypt is essentially impossible for now. Removal: Removing the virus itself is trivial, but no antivirus product (or any product, for that matter), will be able to decrypt the files until the private key is found. File Recovery: There are only a handful of options for recovering encrypted files, and they all rely on either having System Restore/VSS turned on or having a backup disconnected from the infected machine. Cloud backup solutions without versioning are no good against this as they will commit the encrypted files to the cloud. I had a Carbonite employee message me regarding my earlier statement that Carbonite is no good against this virus. It turns out that versioning is included in all Carbonite plans and support all agent OSes except Mac OS X which is outside the scope of this thread anyway. They have the ability to do a mass reversion of files, but you must call tech support and upon mentioning CryptoLocker you will be escalated to a tier 3 tech. They do not mention this ability on the site due to the potential for damage a mass reversion could do if done inadvertently. These are my own findings, independent of what the employee told me. Crashplan and other versioning-based backup solutions such as SonicWALL CDP should also work fine provided the backups are running normally. Using the "Previous Versions" tab of the file properties is a cheap test, and has had mixed results. Using ShadowExplorer on Vista-8 will give you a much easier graphical frontend for restoring large amounts of files at once (though this will not help with mapped drives, you'd need to run it on the server in that case). Undelete software doesn't work as it encrypts the files in place on the hard drive, there is no copying going on. The big takeaway is that cold-storage backups are good, and they will make this whole process laughably easy to resolve. Prevention: As this post has attracted many home users, I'll put at the top that MalwareBytes Pro, Avast! Free and Avast! Pro (defs 131016-0 16.10.2013 or later) will prevent the virus from running. For sysadmins in a domain environment, one way to prevent this and many other viruses is to set up software restriction policies (SRPs) to disallow the executing of .exe files from AppData/Roaming. Grinler explains how to set up the policy here. Visual example. The rule covering %AppData%\*\*.exe is necessary for the current variant. The SRP will apply to domain admins after either the GP timer hits or a reboot, gpupdate /force does not enforce it immediately. There is almost no collateral damage to the SRP. Dropbox and Chrome are not effected. Spotify may be affected, not sure. I don't use it. Making shares read-only will mitigate the risk of having sensitive data on the server encrypted. Forecast: The reports of infections have risen from ~1,300 google results for cryptolocker to over 150,000 in a month. This virus is really ugly, really efficient, and really hard to stop until it's too late. It's also very successful in getting people to pay, which funds the creation of a new variant that plugs what few holes have been found. I don't like where this is headed. Some edits below are now redundant, but many contain useful information. 9/17 EDIT: All 9/17 edits are now covered under Prevention. 10/10 EDIT: Google matches for CryptoLocker are up 40% in the last week, and I'm getting 5-10 new posts a day on this thread, so I thought I'd update it with some interesting finds from fellow Redditors.
soulscore reports that setting the BIOS clock back in time added time to his cryptolocker ransom. Confirmed that the timer extends with the machine offline, but that may be cosmetic and I don't like your chances of this actually helping if your timer runs out on the server side.
Spinal33 reports that AV companies are catching up with CryptoLocker and are blocking websites that are spawned in the virus's domain generation algorithm. This effectively means that some people are locked out of the ability to even pay the ransom. (Technically they could, but the virus couldn't call home.)
Malwarebytes is claiming that MBAM Pro will catch CryptoLocker. If someone wants to test them on it, be my guest. Confirmed
CANT_ARGUE_DAT_LOGIC gave some insight on the method the virus uses when choosing what to infect. It simply goes through folders alphabetically and encrypts all files that match the filemasks towards the top of this post. If you are lucky enough to catch it in the act of encrypting and pull the network connection, the CryptoLocker message will pop up immediately and the countdown will begin. Helpful in determining what will need to be taken into account for decryption.
EDIT 2: We had a customer that ignored our warning email get infected so I will have my hands on an infected PC today, hope to have some useful info to bring back. 10/10 MEGA EDIT: I now have an active CryptoLocker specimen on my bench. I want to run down some things I've found:
On WinXP at least, the nested SRP rule is necessary to prevent infection. The path rule needs to be %AppData%\*\*.exe
Once the program runs it spawns two more executables with random names in %userprofile%. Adding a SRP to cover %userprofile%\*.exe may be desired, though this will prevent GoToMyPC from running at a bare minimum.
This user was a local administrator, and CryptoLocker was able to encrypt files in other user's directories, though it did not spawn the executables anywhere but the user that triggered the infection. When logged in under a different account there is no indication that a timer is running.
The environment has server shares but no mapped drives and the shared data was not touched, even though a desktop shortcut would've taken the virus to a share. I suspect that will be covered in the next iteration.
The list of masks above does not appear to be totally complete. PDF files were encrypted and were not originally part of the set of file masks. That is the only exception I noticed, everything else follows the list. Conveniently (/s), CryptoLocker has a button you can click that shows the list of files it's encrypted.
The current ransom is $300 by MoneyPak or 2BTC, which at the time of writing would be $280 and change.
Fabian reported that registry data is stored at HKCU/Software/CryptoLocker. I cannot glean the meaning of the DWORD values on files but I do notice they are unique, likely salts for the individual files. I'm curious what purpose that would serve if the private key was revealed as the salts would be useless.
I have confirmed the message soulscore left that setting the BIOS timer back a few hours adds an equal amount of time. No telling whether that will work once it has a network connection and can see the C&C server, though.
The virus walked right through an up-to-date version of GFI Vipre. It appears AV companies either consider the risk too low to update definitions or, more likely, they're having trouble creating heuristic patterns that don't cause a lot of collateral damage.
10/11 EDIT: I ran Daphne on the infected PC to get a better idea of what might be going on. lsass.exe is running like crazy. Computer's had it's CPU pegged all day. I noticed the primary executable running from %AppData% has a switch on the end of the run command, which in my case is /w000000EC. No idea what that means. 10/15 EDIT: I just wanted to thank all the redditors that have submitted information on this. I have some interesting new developments that I'll be editing in full tomorrow. 10/18 EDIT: Hello arstechnica! Please read through comments before posting a question as there's a very good chance it's been answered. New developments since 10/15:
We have confirmation that both Malwarebytes Antimalware Pro and Avast Free and Pro will stop CryptoLocker from running. My personal choice of the two is MBAM Pro but research on your own, AV Comparatives is a wonderful resource.
We have reports of a new vector of infection, Java. This is hardly surprising as Zeus was already being transmitted in this fashion, but Maybe_Forged reports contracting the virus with a honeypot VM in this manner.
zfs_balla made a hell of a first post on reddit, giving us a lot of insight to the behavior of the decryption process, and answered a frequently-asked question. I'm paraphrasing below.
A file encrypted twice and decrypted once is still garbage. The waiting for payment confirmation screen stayed up for 16 days before a decryption began, so don't lose hope if it's been up a while. The DWORD values in the registry have no bearing on decryption. Renaming an encrypted file to one on the list in the registry will decrypt it. However, I would presume this would only work for files that the virus encrypted on that machine as the public key is different with every infection. Adding any new matching files to somewhere the virus has access will cause them to be encrypted, even at the "waiting for payment confirmation" screen. Be careful. Hitting "Cancel" on a file that can't be found doesn't cancel the entire decryption, just that file.
EDIT 2: I've rewritten the bulk of this post so people don't have to slog through edits for important information. 10/21 EDIT: Two noteworthy edits. One is regarding Carbonite, which is apparently a viable backup option for this, it is covered under File Recovery. The other is regarding a piece of software called CryptoPrevent. I have not tried it, but according to the developer's website it blocks %localappdata%\*.exe and %localappdata%\*\*.exe which is not necessary for the current variant and will inflict quite a bit of collateral damage. I have no reason right now to doubt the legitimacy of the program, but be aware of the tradeoffs going in. I'm now at the 15000 character limit. Wat do?
Hi Bitcoiners! I’m back with the seventh monthly Bitcoin news recap. Last month's post got very little love, and I don't expect much more success with everyone focussing on August 1st, but here it is nonetheless. In my eyes definitely one of the most eventful months in Bitcoin's history, absolutely unreal how much happened:
SegWit activation imminent
Epic analysis of spam attacks & a 10M-user LN network
2013 price buble & Mt. Gox hack reveals
BTC-e went down
Bitcoin sign guy
Steepest rises and crashes USD-wise
To name a few. For those unfamiliar with the monthly recap, each day I pick out the most popularelevant/interesting stories in bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in bitcoin over the past month. You can see recaps of the previous months on Bitcoinsnippets.com If you're on mobile and can't see the links below, check the web version. A recap of Bitcoin in July 2017
According to our investigation up to the date of this report, the status of the bankruptcy estate is as shown in the List of Assets and the Balance Sheet, and the balance in the account that I have secured as of September 26, 2017, is JPY 1,213,801,185, i.e., an increase of approximately JPY 183,000,000 from the time of the 8th creditors’ meeting.
Status of BTC managed
The amount of BTC managed by the bankruptcy estate as of September 21, 2017, is 202,185.36428254 BTC. Currently, I am still investigating the existence of additional BTC held by the bankrupt entity.
The amount of Bitcoin Cash managed by the bankruptcy estate as of September 21, 2017, is 202,185.36428254 BCC.
Status of Filing of Bankruptcy Claims and Acceptance or Rejection of Claims
With respect to 142 petitions for assessment, the total amount of which is JPY 2,223,322,737 (principal amount only), court decisions have been made for all of them to date, and all of them have accepted my assertions.
Status of Filings of Claims Other than Bankruptcy Claims Related to Exchange
With respect to creditors who filed claims other than the Bankruptcy Claims Related to Exchange, these claims have been accepted or rejected at the investigation of claims that was held on September 9, 2015; however, two creditors filed petitions for a bankruptcy claim assessment, and the assessment is currently under way.
Probability of Distribution
Now that all bankruptcy claims have been accepted or rejected, henceforth, I wish to proceed to the distribution process as soon as possible. However, the detailed schedule thereof will inevitably be affected, among others, by each creditor’s response to the acceptance or rejection of his or her claim. Therefore, at present, the matters such as the possibility of carrying out a distribution and the timing and method thereof have not yet been determined.
I will continue to consider whether, in the case where a distribution is possible, a distribution will be made by way of distributing BTC.
Hi Bitcoiners! I’m back with the third monthly Bitcoin news recap. For those unfamiliar, each day I pick out the most popularelevant/interesting stories in bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in bitcoin over the past month. Now archived on Bitcoinsnippets.com As promised, I launched a website as an archive, where I post the version with links to the original posts and discussions so this post doesn't get auto-moderated. Special thanks goes out to Bitttburger for thinking of the name Bitcoin Snippets. I went back in time and made an overview for December 2016 too. I’ll probably make recaps of 1-2 previous months for each month I progress, so that I eventually end up with everything in a few years. Starting from this month, I’m going to cut back on including memes, there’s too many and they overtake the interesting news. A recap of March 2017 in bitcoin Version with links on Bitcoinsnippets.com

Thanks to everyone who contributed to Bitcoin in a positive way this month!
NOTE: I'm trying my best but because of the sheer volume of tidbits popping up every day, this post might ocasionally miss some updates. Please feel free to point it out in the comments whenever you feel there is information missing in the post, thanks! A note on recovering funds: We have no information on how to recover fiat/bitcoins/goxcoins yet and MtGox has only given very vague statements so far. It is speculated Mark Karpeles (CEO of MtGox) is currently figuring out what to do and not flying to the Bahamas with our money. It is advisable to have patience and wait for new developments on the subject for the time being. March 26th, 2014
Following its application for commencement of civil rehabilitation, MtGox Co., Ltd. consulted with the metropolitan police department with regard to the disappearance of bitcoins which is one of the causes for said application. MtGox Co., Ltd. hereby announces that it has submitted necessary electronic records and other related documents. MtGox Co., Ltd. intends to fully cooperate with each competent authority. Further, MtGox Co., Ltd. continues to make efforts to clarify facts as quickly as possible and to recover from damages.
Match 25th, 2014 A new rumor has surfaced twitter, currently unsubstantiated, from @CanarslanEren who according to his previous tweets would have previously either guessed correctly or know in advance about the recovered 200K BTC (emphasis mine):
Within a few days(or hours) @MtGox will announce that "they found ~670.000 #bitcoin & may release some BTCs to the victims. @PatronaPartners
There's a new update on mtgox.com confirming the previous story of having recovered 200K BTC that were thought lost. Key points:
On March 7, 2014, MtGox Co., Ltd. confirmed that an oldn format wallet which was used prior to June 2011 held a balance of approximately 200,000 BTC (199,999.99 BTC)
For security reasons, the 200,000 BTC which were at first on the 7th moved to online wallets were moved between the 14 th and the 15th to offline wallets.
The bitcoins held today by MtGox Co., Ltd. amount to a total of approximately 202,000 BTC, including the above 200,000 BTC and the approximately 2,000 BTC which existed prior to the application for commencement of a civil rehabilitation proceeding.
March 20th, 2014
Several users were reporting issues with the balance-checking tool online at mtgox.com, namely that bank transfers and transactions stuck in progress were not showing. This is now apparently fixed and balances seem to have been accordingly updated. Thread here.
In line with the blockchain movements we've seen for the past few weeks and the respective MtGox API activity, finally a japanese news article appeared where MtGox lawyers announce MtGox has found and owns 200K BTC, translation, courtesy of h1d:
Bitcoin exchange Mt.Gox which collapsed in February announced on 20th that they have found they're still in possession of the 200,000 BTC out of the 850,000 BTC that was reported to be lost. According to the lawyer, they found them on the 7th of this month by searching through a storage on the internet called a "wallet" which was being used by MtGox up until June 2011. MtGox has reported that they have lost almost all of the 850,000 BTC owned while filing for bankruptcy protection on February 28th.
A new update on mtgox.com is now online: account holders can now provide their login authentication data on the site to retrieve the last status of their wallets for convenience. It would appear that this update is legimitate, Redditcoinstates:
I just called the MtGox call centre in Japan - they confirmed that the login has been put there by "legal" and they have not been hacked. I called this number from the original banckrupty announcement (I called from Australia - we are only 2 hours ahead): +81 3-4588-3922. A nice man with an American accent said that the login has been put there by "legal" for users to check their balances and that the website has not been hacked.
Redditcoin asked for transaction history data as well:
I called the number again (about an hour later) - again, absolutely no waiting - I called again to ask about my transaction history. The same man answered, with the American accent (although sounded Japanese), who spoke impeccable English. He said that the transaction history is still unavailable because the courts still have to "polish" it (whatever that means). I said I needed it for taxation purposes. He replied by saying he will "check on this, and post an update on the website soon".
As for the balance data that can now be retrieved on mtgox.com, the site notes (emphasis mine):
This balance confirmation service is provided on this site only for the convenience of all users. Please be aware that confirming the balance on this site does not constitute a filing of rehabilitation claims under the civil rehabilitation procedure and note that the balance amounts shown on this site should also not be considered an acknowledgment by MtGox Co., Ltd. of the amount of any rehabilitation claims of users. Rehabilitation claims under a civil rehabilitation procedure become confirmed from a filing which is followed by an investigation procedure. The method for filing claims will be published on this site as soon as we will be in situation to announce it.
The MtGox API which used to list pending transactions has been removed today. In the past few weeks, this API had shown that the hundreds of thousands of BTC moving in the blockchain connected with MtGox wallets could still belong to Gox. Thread.
we are working on resuming service, can't say how soon it'll be
While the authenticity is still in question, if true this would be in line with all the rumors and hints we've seen up until now. March 15, 2014
The hundreds of thousands of coins moving in the blockchain that MtGox allegedly still own have been spotted doing something new: the outputs are now merging in new addresses of 2K BTC each. This was first spotted in this thread and later confirmed here. As usual, we have zero indications of what this means yet. -Mahnspeculates:
The only thing I can imagine myself is that whoever is doing the splitting decided 50 BTC was too little or would take too long and switched to bigger outputs per address.
New movement in the MtGox order book as reported by their still online API has been detected. Thread.
March 14th, 2014 There's a new update on mtgox.com concerning their Chapter 15 US filing. It contains no new information other than the confirmation of the news that appeared on March 11th. March 12th, 2014
MtGox US subsidiary assets have been temporarily frozen by US Judge. Story here.
"On February 7, 2014, all bitcoin withdrawals were halted by MtGox due to the theft or disappearance of hundreds of thousands of bitcoins owned by MtGox customers as well as MtGox itself. The cause of the theft or disappearance is the subject of intensive investigation by me and others -- as of the present time I believe it was caused or related to a defect or "bug" in the bitcoin software algorithm, which was exploited by one or more persons who had "hacked" the bitcoin network. On February 24, 2014, MtGox suspended all trading after internal investigations discovered a loss of 744,408 bitcoins presumably from this method of theft. These events caused among others MtGox to become insolvent and to file the Japan Proceeding."
So, DogeHouse is splitting - if you're looking for a new pool, try the P2Pool network
Hello fellow shibes ! You might have heard that DogeHouse (a very big pool, if not the biggest) is splitting into two separate pools. I am writing this post to suggest you an alternat--
What ?? Nobody told me that DogeHouse was closing ! What is going to happen to the Doge I stored there ?!
Well, that's not the point of this post, but don't worry - you can still hurry and do a manual payout here (Smiba said the accounts will stay available for 24h). You can also read more about the situation here. Also, don't store Dogecoins in a pool or exchange, unless you know what you're doing. Remember what happened to our Bitcoin friends with MtGox ? Yeah, we definitely don't want that to happen again with Dogecoin. Anyway, back to the point. If you were mining on DogeHouse, you don't want to choose between the two new pools, and you want to keep torturing your GPU mining, you might want to try P2Pool.
What the hell is a P2Pool ?
To put it simply, the P2Pool network is a decentralized mining pool, constituted of several nodes working together. This allows for better latency if you use a node hosted near your city or country. Also, if a node goes dark, only a portion of the overall network will be disabled - which means the Dogecoin network will suffer less than if a big pool like DogeHouse suddenly goes offline.
Yeah that's cool and all but why would I personally want to switch to a P2Pool ?
There are several benefits to using a P2Pool. I already explained the advantages of P2Pool for Dogecoin itself ; there are also bonuses on a more personal basis. First of all, you don't need to register an account at all ; you just pick a node and configure your miners with the node's hostname and your wallet adress. For instance :
That's all. You obviously will want to change the node (see below if you need to pick one) and the address (without the ). The password field is also completely indifferent, since no registration is needed. Secondly, if you were having latency problems with a previous pool, you may find increased performances with P2Pool (since you will want to choose a node closer to where you mine). Thirdly, the payouts are instantaneous and automatic ; you don't need to reach a fixed Doge threshold to have an automatic pay, and you don't need to pay an even more expensive fee to do a "manual payout". Your Doge will be transferred as soon as a block is mined. Also, the fees on the P2Pool nodes are usually a bit lower (through this will not significantly alter your earnings in itself). Last but not least, some shibes reported an increase in the Doge earned per day ; I can't exactly say how or why, if this is real, just luck or placebo effect, but this is certainly worth mentioning.
Yeah, right, that's too good to be true... There's got to be a hidden twist in there...
P2Pool does have some downsides, yes - for instance, if you choose a node far from where you live, you will probably have a high ping (the time needed to contact the node) and thus you might see that you earn less Dogecoin than expected. That's why you'll want to choose the nearest node. Also, if you have a really low hashrate (I've seen the value of 100 kH/s mentioned several times), P2Pool might not be for you, since it relies on high speed and frequent shares.
I'm convinced ! Where do I start ?
Great ! First, you'll want to pick the nearest node from where you mine, as said before : this little site will come in handy. Using the first node in the list is generally the best solution since it is the node which is the fastest to ping. If you're unsure, try to refresh (F5) several times and check if the results are coherent. Once you've got your pool, you just have to set your miner as seen before, with the correct host and Dogecoin address. And voilà, you're mining on the P2Pool network ! If you were accustomed to high-hashrate pools, you may have to wait a little more for your transfers - but don't worry, you should have biggest payouts to compensate. If you are totally new to mining, welcome ! Try playing with the -I and --gpu-fan parameters to mine faster. Also, don't let your GPU heat unchecked. 60-70°C is probably the maximum safe temperature if you don't know what you are doing (higher temps are fine with some tricks and risk-taking, but it's a whole other matter). You might also want to read this, although some points might not apply if you use P2Pool. That's all ! If you have any suggestions or corrections, don't hesitate to comment. You might also read more on P2Pools here and here.
EXPOSED: The Secret Scams of Coinbase, Bittrex, Kraken, and BTC-e
This is the best tl;dr I could make, original reduced by 82%. (I'm a bot)
EXPOSED: The Secret Scams of Coinbase, Bittrex, Kraken, and BTC-e. Bitcoin climbed to a record high this past Sunday of 3,041.36, according to CoinDesk. At the same time this drop was occurring, two major bitcoin exchanges: Coinbase and BTC-e, who account for 23% of the bitcoin market, also went offline, preventing investors from being able to manage their currency. BTC-e in fact tweeted that it was hit by distributed denial-of-service attacks, or DDoS. Simultaneously, a new blockchain-based project, known as Bancor, was introduced, absorbing mostly ethereum and bitcoin to create a new currency, known as bancor network tokens. Massive amounts of bitcoin and ethereum were transitioned into a new cryptocurrency known as Bancor. Once again, a transition of wealth, from bitcoin and ethereum into CryptoPing tokens, occured. Mark Karpeles, who is said to be the King of Bitcoin, was a programmer who took over mtgox.com due to its overwhelming traffic of eager bitcoin investors, and was responsible for shaping the world's first popular bitcoin exchange.
InsuredCoin.com - Insurance for BitCoin Transactions and BitCoins held in escrow [Feedback Requested]
Various ideas as to insuring transactions have been brought up in the past on Reddit and elsewhere. See: http://www.reddit.com/Bitcoin/comments/zfpja/bitcoin_insurance_the_start_of_bitcoin_financial/ I've used those ideas to put together a prototype and tried to get some feedback. I've had a posting on my behalf in a different sub-reddit and I'm posting here now as I've taken advice on and offline and used to modify the business model. The biggest problem I've seen facing adoption of BitCoin is the risk associated with using BitCoin. This is alleviated with some "credit rating" systems for P2P traders and what-not. The actual insuring procedure is still being fleshed out but: (a) businesses contract with the insuring company paying nominal fees. In exchange, they are certified by adhering to certain security standards IF they are insurable (their net monthly transactions should not constitute a significant portion of InsuredCoin's assets). [The implication is that as a starting stage - we can insure smaller businesses or new adopters, but not something on the level of MtGox or BCGE or Silk Road (as examples).] (b) these same businesses come to legal agreements with the insuring company and provide self-identifying information to the insurer. In this way, they still don't have to expose themselves to the many users (unless their business erupts in scandal) but provide their social collateral to a third-party in case something goes wrong. (c) Finally, as a result, the transactions of end-users are insured against massive system failure for free. Examples of what I'm talking about are the MtGox/BCGE freeze, the security oversight that resulted in losses at a popular wallet, etc. They have third-party assurance that their amounts in escrow will not be stolen by the vendor and that if something else unfortunate happens, they won't just lose all their holdings. Any high-level feedback or advice would be much appreciated. I plan on posting bounties as well soon. So far:
Somebody with background and writing prowess to draft out a "security measures" document for contracted businesses to follow. These will be policies they're contracted to follow.
Somebody to draft out a pitch that basically goes over everything we offer to businesses
Somebody with an actuarial background in the Seattle area that may be interested in going over the actual risks with me.
My thoughts on Bitcoin's shortcomings and how to overcome them.
Please don't downvote because I said bitcoin has shortcomings, hear me out first. First and foremost, bitcoin is an awesome idea and so far, implemented quite well. However, I'd like to discuss some of the shortcomings the technology has and ways we can help bitcoin to alleviate these. First, bitcoin has to be attractive to the general public. Too many times when discussing bitcoin to people, they already know about the miners and see them as people printing their own money with no restraint and they want in. Then, when they learn that they aren't going to be able to print their own money, they want nothing to do with the currency as a whole. How do we solve this? Make sure to make a distinction between mining and using the currency at all. Explain it like the mint and VISA combined; they release currency into the market and process transactions. Eventually, all bitcoins will have been "found" and they will just be VISA, processing transactions and pocketing the tx fees, which will be much easier to explain. Bitcoin needs to be lauded as a currency, not a "get rich quick" scheme. Talk about how bitcoin can replace paypal, western union, etc and talk about how it can virtually eliminate fraud online and offline. Make it attractive to the end users, including merchants. They will ultimately decide bitcoin's fate. Additionally, one underrepresented topic is the fact that "tainted" bitcoins are traceable until the end of time. Say someone goes out and pays a hitman in bitcoin. No matter what the hitman does, he cannot spend that bitcoin with a buyer who will cooperate with the authorities, because they will be able to identify him. Additionally, once one buyer cooperates with authorities regarding "tainted" BTC, the chain can be worked backwards to determine the origin of the BTC and ultimately, the person who broke the law in the first place. I'd imagine governments could be sold on this idea alone, as it could remove the financial incentive for many crimes. What are some other talking points for bitcoin that can make it more attractive to end-users? Second, the blockchain is a huge problem. The idea behind it is fantastic, and it should never go away. But it's a "low-hanging fruit" for entities who do not think bitcoin should be adopted, because what happens if a copyrighted piece of data makes itnow that illegal, unnecessary data has made it onto the blockchain? This has already happened with some megabytes of wikileak cables. Having copyrighted data in the blockchain would mean the entire blockchain could be subject to DMCA takedown requests and every miner and user of bitcoin with the full blockchain stored (which is a majority of them) could be infringing copyright. I welcome suggestions for combatting this problem specifically because I think it's one of our most urgent issues. Third, MtGox. Bitcoin is a decentralized, p2p currency with what amounts to a central exchange. This needs to change. My idea is to have some sort of Craigslist-type site where you can exchange bitcoin for both local currency and goods/services/favors. The site need not deal in bitcoin at all, as there are already methods implemented in bitcoin for making a transaction that is in everyone's best interests with a lower chance of fraud. Please post your own thoughts on bitcoin and possible solutions to these problems. Also, please let me know if I misunderstand a part of bitcoin; I've read into it as much as possible but I'm not a technical expert by any means and I would love to know if I'm incorrect. EDIT: Sorry if this makes my post ridiculously long, but I thought more about the MtGox problem, and it boils down to this: **MtGox provides two main services: 1. The exchange of bitcoin into other currencies. 2. A way to measure the exchange rate between bitcoin and these currencies to ensure a fair market price. How do we decentralize this? I think I may have a solution, and it only requires the bitcoin protocol so thus is immune to DDoS. As a seller, you create a small transaction with additional data listing the amount of BTC you wish to sell and the price in whatever other currency you want for it, and wait. Then, when buyers wish to purchase BTC, they can create a special transaction that includes maybe some contact info that "locks" the transaction from seller to buyer. In this stage, the BTC cannot be spent by anyone. Then, the seller contacts the buyer and arranges the exchange. Ideally, these would be geographically near each other, but this does not necessarily have to be the case. After the exchange has taken place, the buyer signs a message requesting the transaction be "unlocked". Then, the seller similarily does the same, and the BTC is transferred. This ensures both parties remain honest as if both parties do not include the signed message, the BTC is unable to be spent, ever. It's a start but there are obvious flaws: First, a malicious seller could receive the funds and not unlock the BTC. I have not figured out a better way to create these transactions that does not include either a 1. middleman or 2. more investment than just the BTC to be sold and the currency to pay for it. I welcome suggestions and improvements. If implemented correctly, this could serve as a full replacement for MtGox as the transactions are out in the open and any bitcoin client can give you up-to-the-minute details of what trades are actually happening in a specific currency. Additionally, bitcoin has a problem where it's value fluctuates wildly. Sellers want this value to go up, buyers want it to go down, but I think both sellers and buyers would prefer if it didn't do anything else, they'd prefer it to stay the same. To that end, I propose a solution where collectively we value bitcoin based on something other than a fiat currency, like possibly Gold. Gold has a exchange rate to any currency in the world and its value is (for the most part) stable because it's a limited resource. If this were implemented, we could say 1,000BTC = 1 troy ounce of gold or something similar. This has both good and bad; first, the MtGox proposal above would not work the same in this scenario, but in exchange we would have a way to actually provide value to BTC that every person on the planet could agree on. Other issues worth mentioning that I won't cover for the sake of the size of my post unless people want to hear my thoughts and possible solutions on.
The ballooning size of the blockchain
Hashrate of the network skyrocketing (both a good and bad thing, depending on who you are)
The technical barriers to actually using bitcoin
The negative media surrounding bitcoin, and the vulnerability of online wallets
The lack of bitcoin insurance, making losing your bitcoin permanent (losing your key or having your BTC stolen)
With the apparent shutdown of MtGox, BitCoin is about to enter into an interesting phase. My question is this; What does the short term have in store? Now there's no doubt that a big deal is going to be made of the MtGox thing. It already has IMO. People lost money. Some people lost a lot of money. With the rapid emergence of BitCoin into the public eye, and the questions being asked about how, why, and to what end it could be implemented, there's no way that a major exchange going offline won't cause a stir. But information about such things travels relatively slowly to the wider audience. So, what happens next? The way I see it, there are three options. Option one, some people cut their losses, sell out, the price drops a bit, and then goes back to normal levels, steadily increasing as it was (kind of). This is probably one of the more predictable (I don't want to say likely) options. Option two, as information is spread via the media and whatever, people panic. Lots sell, the price bombs, and whoever's left has to pick up the pieces. I honestly hope this is what happens, because it creates bloody good opportunities for gain in the long run, if BTC is to be a long term currency. But it will be extremely scary for those who hold a fair amount of coins. And finally, option three. People buy heavily due to the increased awareness from the media while only a few sell out, the price goes up significantly. There is, of course, an ever present option 4, that it dies completely. But I think that only a major security flaw would scare the market like that, and it doesn't seem likely yet. Thoughts?
Jon from WickedFire & His Conversation with Mt.Gox CEO Mark Karpeles
From Jon admin of Wickedfire - My full unedited conversation with Mark... -excuse the formatting- looks good here until you post it..then it scrambles all the text eggs. Here is the original source which is easier to read. http://www.wickedfire.com/shooting-shit/179038-my-conversation-mark-karpeles-mtgox.html I removed the channel name and my IP info along with the person who created the channel that does not want to be on record for this. This conversation took place on 02-25-2014 at 10:39am EST. [10:39] == JonWickedFire [IP REDACTED] has joined CHANNELNAME [10:40] == mode/CHANNELNAME [10:47] == MagicalTux [[email protected]/staff/MagicalTux] has joined CHANNELNAME [10:48] Hey Mark. [10:48] Thanks for coming in.. I know you're a bit.. shaken up and stressed.. [10:51] hi [10:51] Are you doing okay? [10:52] more or less [10:52] it's 1am and tomorrow morning first time I have a lawyer appointment [10:52] things couldn't be better [10:52] (well, not tomorrow but today, now) [10:53] Yeah, you're in the future over there in Japan, lol. [10:53] guys in NZ are even more in the future [10:54] Yeah two places I've wanted to visit but cringe at the flight time alone. [10:55] So I just wanted to talk to you on here, no pressure, you don't have to answer anything you don't want to. I'm not a journalist. [10:55] We've chatted before briefly. So you know a lil something on me. [10:56] yep [10:56] And with all of what happened yesterday, even though I knew all of that, I didn't let me contacts at FOX Business publish it, because I didn't want to see bitcoin or gox going up in flames if it could be salvaged. [10:57] Obviously holding that info back and not publishing a tumblr or leaking docs first allowed someone else to stake a claim on it first. [10:58] But you win some you lose some.. and honestly, I'm not a fan of people posting things that are rumors or bullshit or not verified just because it damages the shit out of someone or a company... and it really cannot be taken back afterwards. [10:58] Is that Crisis Strategy Draft even legit? [11:04] more or less [11:05] as the name suggests it's a draft, and it's a bunch of proposals to deal with the issue at hand, not things that are actually planned and/or done [11:06] this said this document was not produced by MtGox [11:07] I saw some strategies in there that I had shared with you, but also saw some things in there that I would have never suggested anyone ever go through with as it would make you look horrible.. [11:07] I think a lot of people ignored the draft part. [11:08] It was just really surprising to see that being "leaked".. [11:10] Do you think it was leaked by someone purposely to hurt you personally or gox in general? [11:13] [01:09:51] Do you think it was leaked by someone purposely to hurt you personally or gox in general? <- I have some doubts [11:14] Heh, I bet. [11:17] Are you stepping down as CEO and away from gox too? [11:17] (If you can't legally disclose, then just say so) [11:20] can't disclose that yety [11:20] yet [11:20] K np. [11:22] The reason I'm asking is because after yesterday's events of you removing yourself from the foundation and deleting the Twitter account/posts and all.. right away speculation within the bitcoin arena went into hyper chaotic mode, and the word on the street was that you were closing up shop and running away with all of their monies and bitcoin... [11:22] How does that make you feel to hear or see people you bailed out yourself and stood up for over the years, turn on you like that? [11:22] not good [11:24] Mark, I know you're not one for expressing yourself, but here's your chance at it, because you really have stepped up before, and done things NO ONE else ever had.. or probably will again.. and it seems like all of it has been quickly forgotten and instead you're being labeled as the Madoff of bitcoin. [11:25] We're having this chat, and you're still in Japan at your apt/office and not in a cave somewhere, right? [11:34] Look Mark, you took mtgox and ran with it, built on it, stuck with it and took it to a level no one ever thought possible. When other exchanges were crippled, you stepped in and bailed them out or absorbed them to save the bitcoin market in general. In exchange it brought you a massive surge of customers and press that made you look like the hero of the day and then some. [11:34] But what most people forget too was that you weren't set up to handle this from the start.. [11:35] [01:25:02] We're having this chat, and you're still in Japan at your apt/office and not in a cave somewhere, right? <- at home, with my cat being a pain sleeping on the keyboard [11:35] Yeah, doesn't sound like someone on the run with bags of money... [11:37] What's the plan now for you and mtgox? [11:37] can't comment on that yet [11:37] Alright. [11:37] (mostly because doing so could compromise our current efforts) [11:38] imgur: the simple image sharer <- my cat pushing my keyboard, me pushing the keyboard back on the desk [11:38] So you guys are still actively trying to save it though? [11:38] We haven't given up [11:40] You could have given up and walked away a bunch of times previously, but you always stuck it out... even though others have closed up and walked away, why have you continued to fight and work at it and not give up? [11:41] "Giving up" is not part of how I usually do things [11:42] Do you want to tell your side of this a bit more? [11:43] Like what you've sacrificed or given up, personally? I have to imagine it's taken quite a toll on you. [11:43] well, first I would guess is my health [11:43] What do you mean? [11:44] took on more than 30kg since handling MtGox [11:44] (compensating for stress by eating) [11:47] I'm guessing stress from lack of sleep too, like now.. [11:48] heh [11:48] and drinking liters of coca cola [11:48] how american [11:48] (almost american, actually, since some people see coca cola as being non-american) [11:52] lol [11:54] anyway [11:54] I should try to get some sleep [11:55] already 2am [11:55] waking up in 4 hours [11:55] Err [11:55] One more thing.. [11:55] and starting to be tired of pushing my keyboard so it stays on the desk [11:56] Do you still believe in the viability of an unregulated digital currency like bitcoin tho? [11:57] difficult [11:57] tbqh the pressure we got from banks and governments makes things very hard [11:58] Do you think if it were regulated it would make it easier to work things out? [11:58] partially [11:58] How so? [11:59] well, first avoid being blocked by banks and governments around the world [11:59] if regulated, it means that as long as you follow the regulations you're fine [12:00] The biggest question people really have asked though is are you personally vested in mtgox with your own btc? [12:01] And whether or not you, like everyone else, have taken a personal hit and are in the same boat as they are in terms of taking a loss/hit from the recent events? [12:01] [02:00:59] And whether or not you, like everyone else, have taken a personal hit and are in the same boat as they are in terms of taking a loss/hit from the recent events? <- any BTC I own personally were on MtGox [12:02] How much did you lose yourself? [12:04] Well, technically speaking it's not "lost" just yet, just temporarily unavailable [12:05] == MagicalTux [[email protected]/staff/MagicalTux] [12:05] == realname : Mark Karpeles [12:05] == channels : CHANNELNAME [12:05] == server : calvino.freenode.net [Milan, IT] [12:05] == account : magicaltux [12:05] == End of WHOIS [12:05] Well, how much is unavail for you? [12:06] I'm not even sure [12:06] Guys on Reddit and WickedFire are running around posting screenshots of horror stories about how much bitcoin they have lost from this.. [12:06] didn't check my wallet before pushing the site offline [12:07] anyway [12:07] maybe I should go to sleep now [12:07] Anything else you'd like to say to everyone before all the pissed off people start going nuts, even more...? [12:09] not really [12:09] maybe just a link? something like that: Why do we fall? - 9GAG [12:09] well, we'll see how this one goes anyway [12:16] Well, I'd like to chat more, but I know you're pushing to go to sleep. [12:17] And so long as you are saying you're not disappearing from this.. that's okay. [12:17] I still think you should say something more to all these people or at least reveal how much you've taken a hit for, personally.. [12:17] It would show them that you are still on their side. [12:19] By the way, that whole removal from the foundation, did you decide to leave that before or after the chats with them to help save gox versus let it fail?
Not actively moving your coins out of MtGox? Here is a simple way to keep your account safer.
Change your password every 24 hours. It prevents bitcoin withdrawls for 24 hours. Ideally you'd change it before 24 hours ... but if you need your coins you can move them in 24 hours. It's simple. If you lose the password MtGox makes it easy to recover access to your account. This is not a replacement for other security measures, just in addition. I recommend using a dedicated machine. If you don't have access boot linux from a CD and use a usb key. If you want to be really paranoid disable your normal harddrive either by unplugging it or maybe in the bios. Your dedicated machine... use linux.. its simple enough to use for only dealing with coin related stuff. Use offline paper wallets. Please read this also check out this video Use 2 factor auth everywhere. Get a Yubikey if possible. Seriously dedicated machine that goes to google, mtgox, campbx and whatever exchanges you use and absolutely nothing else.
