Yobit is a scam they keep their Wallets on maintenance indefinitely and will not allow you to withdraw their old coins. I have been trying to withdraw my OMG coins without any luck for over 6 weeks now they don't respond to any of their support tickets or telegram Channel
6 weeks? That's too much for waiting for your withdrawal, I wonder why you keep on remaining faithful to that exchange even though a lot of problems are existing. There's no reason for me to keep on using them, their support sucks and they don't intend to value their customer or even give us a welled customer service.
