But I also did a backup of my bitcoin wallet.Now I want to sell these bitcoins but when I went to the site, the official client was different and very heavy.And the site was showing as first option Multibit.So, I got Multibit.But I couldn't import the old .dat wallet.Am I missing something?Is there any way to convert the wallet for Multibit?https://blockchain.info/wallet/import-wallet wallet bitcoin-core multibit wallet.dat wallet-recovery up vote 1 down vote Yes, blockchain.info's wallet import is safe.It encrypts things in such a way that not even blockchain.info can access your private keys.You can make transfers from there (it's a sort of online wallet), so you don't even necessarily need to transfer them to MultiBit before wanting to sell them.To quote a previous answer with instructions on importing and then exporting to MultiBit: Visit https://blockchain.info/wallet/import-wallet.Drag the Bitcoin-Qt wallet.dat file into the dotted area.Login to the new wallet.

Under the Backup heading click download.Open multibit choose Tools -> Import Private Keys.Now import the wallet.aes.json file just downloaded.Delete the keys from the blockchain.info wallet.If you don't trust blockchain.info (despite their claims), you could extract the data entirely offline using pywallet and then import it into MultiBit.It should also be possible to dump the private keys from the official client without downloading the whole blockchain (which is the "very heavy" part of it).See How do I import private keys from Bitcoin-qt to Multibit client?for help with that.Once you have access to your bitcoins again and want to sell them, you could sell them on LocalBitcoins.In the US, I can also recommend Coinbase.Did you find this question interesting?Try our newsletter Sign up for our newsletter and get our top new questions delivered to your inbox ().up vote 0 down vote What error did you get from Multibit?If its an error regarding to the file its maybe corrupted.

I am not sure if you can import a .dat.I know for sure that a .wallet and .key will work, but not a .dat.Can you look inside with a text editor, and see whats in it?Anyway the link you posted is as safe as it can be, so you can try that one.You can also try to import another file, like the .key or the .wallet if you still have those.Your Answer Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.Browse other questions tagged wallet bitcoin-core multibit wallet.dat wallet-recovery or ask your own question.Help restoring old wallet.(self.Bitcoin)submitted by Hi guys - I bought a few bitcoins sometime in 2011 through MtGox.I know they went belly up, and I'm not clear on whether or not having a wallet will even make a difference in this situation.However, I just found two old .wallet files from that time period.One file is dated from 12/2011 and a copy of that file is 11/2013 - which probably corresponds to when I switched computers.
