I have been trading with Kucoin and Kumex for 8 months and had a pleasant experience until recently. Kucoin is an elaborate scam. Check the Reddit forums and you’ll see a bunch if users who have had money stolen. Fake sell orders etc. personally, my money was stolen from them in an elaborate but shady way. They didn’t fill my stop limit and I noticed it so I tried doing a market order over 15 times to get out of that position before my money liquidated but of course they prevented me with cancel orders every time until they liquidated me and that was that $1200 gone. In the hands of dishonest exchange owners.
