As for bots, what one could do if they were running a racket is start an army of bots that would promote coin X at time y, then stop them when you think coin X has peaked.
This probably happens, but I doubt the influence of bots is all that huge. They're usually pretty obvious, I mean if you see many different accounts posting identical tweets, you can assume they're managed by the same person.

Bots don't tend to collect 1000s of genuine followers. Not that many people are influenced by them. It's probably more hassle than it's worth, and possibly even counterproductive. I mean, for every person you might suck into a coin, you might scare two off. Managing an army of bots successfully is a skill in its own right.

I'm doing well at PLO right now, up about $1400 since the start of 2021. That's my current kick. But the fun of it to me is learning the complexities of the game and outplaying people, not earning a few extra $. I like winning.
I like winning and making money from home. Not sure how much poker I'd play if I were already wealthy, probably not much other than social games. I strongly suspect I'd still invest in crypto though. I'd see it as a better investment vehicle than other options.
