Trading in yobit is different with day trading of bitcoin in the exchanges.In yobit you can do altcoins trading where you buy and sell altcoins with bitcoins whereas day trading is buying and selling bitcoins only with price is fiat currency and best place for that is localbitcoins.
The required skill set on yobit is much larger, since you deal with many small coins/scam coins. That's why they are listed at yobit and not on a reputable exchange.
If you want to earn with trading wi would rather start with top 20 altcoins on bittrex or poloniex. They got good buy support and for a beginner i find it easier to earn money.
