A friend of mine had some Bitcoin on his phone a couple of years ago and he's lost that phone which stored the private keys on without any other backup. We can see his balance on the blockchain and he knows his password for the private keys. Is there a way of creating the private key from the bitcoin address and the known password?
I think that "some" means a lot of money already today but unfortunately, he lost the very important key that can only open his bitcoin's wallet. There is no other way to get your bitcoin back since the key was lost already unless if your friend made a backup of it. That is why i really made a good backup of my private keys. I saved them in a flashdrive, encrypt them and place them on a place where i only know.
