>How find out what coins are legit and which ones won't make it
no easy way to just tell, it's a bunch of small stuff that you'll notice after spending a lot of time doing research, like Team track record and competences, how team interacts with (potential) investors, tokenomics, if they're trying to fix an actual problem and how they're fixing it.

also look at the shills when it comes to coins, generally its either very low quality memes or very high quality memes, no projects just comes out with a press kit loaded with pepe memes and 4chan shit, if you see that, run.
also its how they talk about it, if one ID just says "sounds legit" and never posts again, its probably not. Most of those threads are circlejerks with "am i going to make it?", "how big is your stack", "when moon" and other price speculation talk, always trying to trigger fomo.
