I check this also in one of the exchanges I am using and tested it. It is quite nice but there is some part I don't understand.
Was that by any chance Kucoin grid bot?
(....)
I only tried the ByBit grid trading bot but yeah I saw there was also a grid trading bot on Kucoin.
That's sad to know for you that you ended up with no profits.
For me, I just tried them for a short period of time with a low amount and no losses as of the moment. But after I pos this thread, I terminate those bots, for now, I want to research more to know how they really work and analyze too.
