Yobit is one of the earliest Russian cryptocurrency exchange. It has a great deal of volume with large variety of coin token and trading pairs. The exchange has its native token (Yo token) with current price value of 0.135btc (not bad in my opinion); holding the token qualifies you for different IEOs launched on the exchange which is a plus for its investors.
I have more than 6 months trading experience with Yobit and I can say I hardly find fault except for the low quality user interface which might be a nightmare for some professional traders and also their slow and unresponsive customer support.
As far as I can recollect, the exchange has provided it users and the whole crypto community with airdrop (free tradable cryptocurrency); I personally earned about $50 from the recent one.
Over all, liquidity on the exchange is high and recently heightens due to the launch of YoDeFi (a liquidity token) system.
