UPDATE: SCAM! BEWARE. They knew that there was a bug, that affected the trades. They won't even pay attention to what I'm saying. ORIGINAL: The app bugged and costed me $600. Support won't answer my emails and avoided me in the online chat. I told it to sale at one price, but it sold at another costing me $600. The next day, I get an alert from kucoin of an error in the servers just like what I experienced...but they won't correct my wrongful loss or even respond to me.
