Guys, thanks for lots of replies :-)
First of all,
1. Lost password = have no fucking idea in details what password I picked on all of the three accounts - I have clue which kind of combos I could use and that is why i try to break it running btcrecover
2. I don't have mnemonic seed cause I didnt care too much about my accounts and I thought I could easily recover my pass
3. I donwloaded my wallets as aes.json -> they hold my password encrypted -> dunno it is a private key (?)
The main problem is that one of the wallets is broken (dunno why), btcrecover cant recognize it and I think it might be the chosen one wallet where is my 1-2 btc
Any ideas guys ?
Looks like you have to contact support, and even then I don't think you stand a good chance getting your wallet back. To be honest, you were quite stupid in not remembering your mnemonic.
Do you have any sort of proof that you own the account? Maybe the corrupted wallet might hold some information that's usable.
But of course, be prepared to not get anything from support, as support centres usually do not recover information unless you have a solid way to prove yourself.
