If they'd just fix their issuers and hire someone bounty manager here, they still can advertise in the forum and it could possibly earn the trust of the users. Yobit has been one of the surviving exchange since time. I can still see users wearing signatures of yobit but pretty sure they are not paid as well. I have chat yobiit support about it they were saying they are paying but checking my account the btc can't be send to my wallet.
They tried to contact yahoo when they got attention initally but they let the buzz about yobit to spread all around the forum and launched their IEO to make profits after that there is no intention from them to pay participants or manager so they just been silent.
