The best thing that can happend is for yobit to be hacked and never come online again.. Would do crypto a big service, mainstream will never happend when such exchanges are around.

I guess you have withdrawn a coin where they have not upgraded their wallets, and it is sent on the old chain. I lost a great amount on that. Doubt support ever will answer.

I will never use yobit again, and will warn people about it. I will neither invest a single cent on coins that is newly is listed or gets listed there in the future.
