Many do not like Yobit, but I have used it for years and it has never given me a problem, they have always answered my support and I really like their system because it is easy to operate.
For small trade Yobit is very good, but if you want to trade with high quantities I recommend Poloniex and Bittrex, they are exchanges with high demands of exchanges and bigger amount of currencies.
Be careful because you are now beginning to create fake exchanges (SCAM) and you may end up at a loss.
