Was that by any chance Kucoin grid bot?

Personally I used a few trading bots but none of them ended up being profitable in the long-term, I had some very short-term gains here and there but it usually lasted a few days max and once volatility became too much bot would start making less and less and eventually position would get into some loss.

My guess is that these bots could work out better in a less volatile pairs/markets so maybe cryptocurrency is not the best option for those automated bots and Forex pairs like AUD/CAD, AUD/USD and some other pairs that don't move up and down that much in a short period of time are a better option, but for trading bots to be profitable in such pairs you got to find a platform with lowest fees since movements are small so are the gains.
