If you are a beginner, then you definitely should not invest based on someone else's recommendations. You are now at such a young age that you have enough time to start studying cryptocurrency, and to understand its advantages and disadvantages. And it is possible that by the next halving you will be able to independently make decisions about which coin you need to invest in.
At a fairly young age, it's lucky you know crypto. I think if he's a beginner then he's still quite a lot of time to learn. In my opinion, of course, BTC, BNB and ETH are the most powerful coins at the moment. I think it's the best option, maybe some new chain like Polygon, which definitely has real uses and has a pretty big fan base with a good history it's a little promising for you to hold on to long term. But that's in my opinion, and not advice for your investments. In addition, I also hope that confidence in Halving is still a guide and the market will change Bulish and reach a new high price followed by all coins. May that cycle continue to repeat itself and continue for the next halving period.
