I used poloniex ( not recommend because it's doesn't update for a long time. so laggy. everything need KYC). now I'm moving on to Binance. don't need to do KYC things and you still can withdraw 2 btc/day.
Binance need KYC when you withdraw
Poloniex is more prudent and too trouble if we trade low vol. , Large vol. trader may love it
