I use Binance, Kucoin etc crypto exchange for Trading, Binance use very often and I use Kucoin very rarely. But my main problem is high eth withdraw fees from Exchange to Personal wallet (MyEtherwallet). Have any crypto exchange with low withdraw fees?
The exchanges themselves are gonna offer similar rates. However, you may be able to get away with transferring with another currency (granted it is on both exchanges). I have used XRP and XLM in the past because they offer low fees to move upon exchanges. Try those out and see if it works.
