Is there any other reason why he's currently FOMO-ing? Is he in need of immediate money or is it because of the bull run?

Expecting instant returns is just a spell for trouble. He's just going to get emotional and once he experiences a market dip, he won't be ready for it and might make him choose bad decisions. He might be better of on investing on something else, like investing on himself.
Personally, if I were in your position I would give him the tools to check out what coins have good potential. I teach them what are the indicators to check out, what red flags to watch out for and give them my sources. I too have a lot of friends asking for this kind of advise and I'm very cautious of what I say. In the end, its their money not mine.
