I can't pick any specific altcoin that I know will have potential, but I believe it will be one of these 3 categories.

1. Layer 2's
2. AI's
3. Layer 1's

TBH, it's pretty hard to pick which coins will have the potential to grow in the future. There are some tokens like SOL, AVAX, ARB, ATOM, ADA, INJ, etc. I guess it would be better for us to do our deep research on which projects we believe will grow a few years from now. What I did is I just bought different altcoins that I believe will grow a few years from now and then invested a few hundred bucks on it. If it become successful then good for me, if it's not then still good.
