i think alcoins aren't good for investing now - i focuse myself on researching interesting defi, especially dex projects - much more credibility and good returns
Practice shows that everything can do a lot of x's and everything can turn out to be a cruel scam. The Defi hype can end quickly as it started quickly.
But in one thing you are right - you need to be where the excitement is at the moment, but you need to know when to get off this train in time.
