first time in exchange. my friend recommended yobit, and i was comfortable using it. now I start switching to etherdelta because my coins are available for exchange. I also always read the reviews of friends before trying the other exchange. this is important so we do not get into the web scam.
Both yobit and etherdelta are not good imo, yobit have many problems and etherdelta is laggy. It's better on kucoin or even hitbtc is more better imo or you can choose binance. It's good for beginner and you don't need verif kyc to trade on these site.
