Trading bots aren't a new thing on this industry. I have been hearing about such promises for several years already. Personally, I never invested in bots or AIs, but I have a perception it's only profitable for the developer or seller, while customers or buyers are just being deceived by a technology which doesn't guarantee any profits after all.
If it worked as people expect it to do, you would be already seeing hundreds of thousands (at least) living from an income made only on automatic mode. Truth is that we don't see these people too often. Actually, I've never seen anyone.
So, why should we believe this time with the brand new AIs it's going to be different? It's all about marketing, nothing else.
