They also offer incentives like there 700 Yoda to get people to there exchange then lock away there airdrop.. only to then steal the BTC and LTC you had on there exchange.
I have no idea what Yoda is, but it sounds like one of their proprietary scam coins that they offer in the investbox thing--correct me if I'm wrong, which I probably am. At this point it seems like they're grasping at straws trying to entice people to trade on Yobit, and I don't think it's going to last for much longer.
over 1000 coins listed and yet only around 12 wallets work, every other wallet is in maintenance.
Twelve wallets might be a serious exaggeration, but I definitely know where you're coming from, and I even started a thread about this exact situation--I don't know what exchanges like Yobit are up to when they keep wallets in perpetual maintenance mode, but it's a shady practice at best. Yobit ought to delist about 75% of what they currently offer, since many coins have zero trading volume and are essentially dead coins.
