I advise dont trade in yobit, there are many shitcoins in yobit.
I once tried to trade in yobit but become bankrupt, trade in ccex
instead. Buy at cheaper price coin like vta, xaur, adcn, hill ect.
For sure youll earn profit well.
Well shitcoins or scams coins are as usual on trading sites even cex have it but unlike yobit there so many .
You have to do a research first about that altcoins before to invest even the hot pairs or trend altcoins are sometimes scam coins too.
Anywhere trading site you trade if you know what coins to invest you will have a profit and you will spot what shitcoins are.
