Still on my quest for the best exchange for me, here before is DragonEX.
DragonEx is a beautiful exchange in terms of site layout and also in services rendered. ONE thing that cannot be over emphasised is its customer service, where response are made available in minutes.
It has interest rate for maker and taker at 0.1% and 0.2% respectively nd operates only with bitcoin, etherium, USDT, dragon tokens, DT.
