Hi bro
can't recommend any coin but yes I can recomend you to study the ecosystem and find out what are the best trends in crypto for you.
point out what can be the game changer, which are the approach that can win in the near future and find out the project that build smth usefoul.

for example blockchain interoperability, security tokens, sidechains, oracles...there is a lot of stuff that we need to understand to find the right project to invest in.

good luck
