If you are still looking for the idea I would suggest you do some R&D about Ethereum, BNB, Trx, Matic & Ada. Even though I am also holding 3 of them but I would suggest you first gain some knowledge about the crypto market and then only invest because investing in others' opinions is not a good idea.
Your saying that "investing because of other people's opinions" is not a good idea, is something I totally agree with mate. everything must start with the courage to carry out their own execution even if one is wrong, of course, it will be used as a lesson in the future.
If you're afraid, you can start with the smallest value and add gradually, of course, that's the best way.
many are already available at CMC if you want to invest, right now all the altcoins are red is a very good time.
If you have a large fund, choose the one with the best ranking, if you have a small fund, you can choose a lower rank, everything is analyzed first, which may be able to move up when bitcoin increases.
