http://docs.bitshares.eu/bitshares/migration/howto-importing-wallet.html looks nothing like the wallet i'm using, Bitshares 2 v 170410.

@xeroc: thank you lots! Will check if this works for me.

Hi berol,

Where did you buy them? Were you an AGS donor?

I'm sorry if the headline is bad (I read in one thread that we should be as precise as possible),  but I'm very unversed with BTS.

Basically I would need to know if it's possible to recover my bitshares if I have the private key of the bitcoin address I bought bitshares with? I read somewhere a while back that it is, but I'm not entirely sure if I remember it right and how it's done. I bought them sometimes in 2014 (I think) and never touched since. Everything else is gone, I just have 2 btc addresses and one of them is the one I bought with. I understand that having the private key of the btc proves the ownership and it might be possible to recover them?

After hours on the forum, reading, I couldn't find anything so if anyone can point me in the right direction, that would be amazing!
