Bitcoin wallet you may need to upgrade
Currencies / Bitcoin
In not too many words: we don’t support any short-term positions just now.
A bug in OpenSSL, used by Bitcoin-Qt/Bitcoin Core, could allow your bitcoins to be stolen. Immediately updating Bitcoin Core to 0.9.1 is required in some cases, especially if you're using 0.9.0.
If you are using the graphical version of 0.9.0 on any platform, you must update immediately. Download here. If you can't update immediately, shut down Bitcoin until you can. If you ever used the payment protocol (you clicked a bitcoin: link and saw a green box in Bitcoin Core's send dialog), then you should consider your wallet to be compromised. Carefully generate an entirely new wallet (not just a new address) and send all of your bitcoins there. Do not delete your old wallet.
If you are using any other version of Bitcoin-Qt/Bitcoin Core, including bitcoind 0.9.0, you are vulnerable only if the rpcssl command-line option is set. If it is not, then no immediate action is required. If it is, and if an attacker could have possibly communicated with the RPC port, then you should consider your wallet to be compromised.
This vulnerability is caused by a critical bug in the OpenSSL library used by Bitcoin Core. Successfully attacking Bitcoin Core by means of this bug seems to be difficult in most cases, and it seems at this point that even successful attacks may be limited, but I recommend taking the above actions just in case.
If you are using a binary version of Bitcoin Core obtained from bitcoin.org or SourceForge, then updating your system's version of OpenSSL will not help. OpenSSL is packaged with the binary on all platforms.
A lot of technicalities here, but the gist of it is – if you’re using the 0.9.0 graphical version of the Bitcoin Core (Bitcoin-Qt) wallet, you must update the software version to 0.9.1 as soon as possible. You can do it here.
Even if you use other software as your wallet, you might have to either update to a new bug-free version or go offline with your wallet and wait for such version to become available. Wallet software using the OpenSSL library is affected. Best check with your software provider if you need to upgrade.
This is not the first bug in Bitcoin wallets, probably not the last one and it has been reported that stealing funds by exploiting this bug might be relatively difficult and of limited impact but it is better to be safe than sorry.
Now, let’s move on to the charts.
On BitStamp, Bitcoin “calmed down” over the weekend with trading subsiding on Saturday and staying relatively peaceful on Sunday. It looked like traders took a weekend break and Bitcoin stayed between $400-450 for the most part of the weekend.
