First of all, don't miss out on the 100x return
Try not to buy when FOMO is at its peak; wait for pullbacks or much calmer levels.
If you say you're diversifying, that's pretty good.
I usually check the cryptos listed on the most popular exchanges (at least six months after their listing) and keep an eye on them to see how they're performing.
If you truly believe in an early-stage project with real utility, not just hype, then I would invest in it, even if it's a small amount, but do it. Always, of course, check the team's track record: if they've worked on other projects, how long they've been involved, and if they've actually delivered.
Right now, you have to be very careful about which cryptos you invest in. More than a thousand new cryptos are launched daily, making it difficult to bet, but I usually let someone else filter them (for example, what I mentioned about exchange listings). These initial filters are only useful if you're expecting something in the medium term.
