I had the same problem , opened a account at their site ... dropped some etherium classic into my account and then after a while i got a email that im withdrawing BTC ... WTF and 6 minuts later this is confirmed without me pressing the confirm button. And i cant log in in my account also if i change my Google 2 F in my phone by deleting it and add it again my login does not work anymore... SCAM the whole Kucoin EXCHANGE !!
