Thank you very much for this mate. While I've already chosen GunBot as my trading bot of choice, it's good to have a site where you can find reviews and other indicators about the different trading bots available. AFAIK, all trading bots require a certain level of investment to be able to use them. If there was a trading bot that I could get for free, it would be even better. But even if there isn't, it's well worth paying the money to obtain a trading bot that supports many popular exchanges.
Personally, I prefer to use trading bots on decentralized exchanges than on centralized exchanges for many obvious reasons. But considering that centralized exchanges have more liquidity than decentralized ones, it's better off to use trading bots there. My coin of choice for automated trades so far is Dogecoin.
Nonetheless, I hope to make good profit by using the trading bots listed here.
