Yobit is not turning out to be scam, it has always been a shitty exchange with shady behavior from day one that it opened up and started advertising on bitcointalk to gain lots of newbies!
besides that seems to be the pattern with ALL the exchanges. they start good and they all end up scamming eventually.
4+ years ago it was Cryptsy that was the biggest exchange that people trusted. it scammed people
3 years ago it was Poloniex and ended up the same place
2 years ago it was Bittrex and ....
now it is Binance....
It's funny hw people recommend these centralized exchange. There is no such thing as trusted exchange as far as keeping your funds on them is concerned. Prosperity will prove us right or wrong on this
Trade on the exchanges with what you can afford to lose. The is one of the most important rules of trading
