yobit is the one of the worst exchange ever. shitcollection cemetery.... STAY AWAY.
So many people say to stay away from yobit, but I disagree. I have never had any problems with it, quite the opposite. I have made plenty of profits thanks to it in the past. True, there are some super shitty shit coins there but nobody forces you to buy/trade/whatever them.
indeed , there are worser exchange , with real scam movements.. been more than 2 years on yobit .. and i am still there ...
only you have to do is , use common sense with trading
