i have seen a bunch but none of them could keep performing well since they aren't really "AI", they are just predefined scripts that perform the same action based on a bunch of conditions that were hardcoded by the developer and since the altcoin market is extremely unpredictable they always end up "confused" and lose you a lot of money. all is needed is a simple dump or even a pump to screw with the bot completely.
I totally agree with you. There's no trading bot that can actually make accurate predictions all of the time. Just like you mentioned, only a simple pump or dump is needed to screw up the bot.
Besides, I do believe that a person who doesn't want to go through the labour of acquiring the necessary skills and knowledge for trading shouldn't have the privilege to trade. If you want to make profits trading, then it means that you should take the necessary time out and learn what trading actually means and how to trade profitably.
