Sharing some comparison between Kucoin exchange and Binance exchange.
Binance trading fee = 0.1% or less 50% when you use bnb for transaction fees = 0.05% trading fee
>>>>> withdrawal fee for btc = 0.0005 btc
Kucoin trading fee = 0.1%
>>>>> withdrawal fee for btc = 0.001 btc
Remember kucoin share has a different ability compared with binance token. If you can get up to 50% discount by using binance token and then you will get dividend by holding kucoin token. But the binance token will be very useful compared with kucoin shares and i will try to choose binance as the best exchange site.
