Hello all,

my friend thinks he has some bitcoin from 2009/2010 on a certain address and wants to recover it. He had a wallet.dat those days but it was deleted on his computer. But he also thinks to know the 24 words.

1.) We wanted to try the words on a ledger but the ledger supports only a fixed set of words.

My question:
Are there other tools or did exist in the past with which he could have generated keys from a free choice of words? And if yes, I suppose we have to find the correct tool which was used in the past?!

2.) We tried to find the wallet.dat in the deleted files on his computer.

My question:
Let's assume we found it, we would have to know, with what tool it was created, right?

Do you have any ideas or remember what were the common tools or applications for that during that time or do you have any other recommendation how to approach this?

Thanks a lot,

Brgds,

Robert
