I do not think so Yobit would let you move out your coins form the exchange. Yobit is one of the most ugliest exchanges which once you store your coins there I am sure it will be impossible to do a withdraw. I lost a lot of money with EGC because I had to sell them on the exchange a very low price. I did it getting BTC and then I had to convert BTC for ETH that was the way I could recover some of my investments. People should avoid Yobit for storing any crypto coin or tokens. Poloniex also became as a shit exchange. About qt wallets it is a big problem and definitely non of them are easy to handle.
