There are large number of options but if you choose top coins then you can earn more profit and one more thing is that do your own investigations also by reading the details of project because everyone thinks differently and timing of holding is different so try to make your own concept by studying overall details.
In my opinion, I will not consider it a good thing like OP is asking for in which coin he/she should invest. what do you think dear is it good to ask like this? But yes i would say OP should consider anyone's advice as a reference for his personal research Sometimes other advice helps but taking direct action on other sayings can be a bad thing. As we know that Investing in altcoin is a very picky part we have to conduct good research before investing in any of these even if they are in the top 100.
On the other hand, Investing in Bitcoin is not as risky as investing in altcoin Bitcoin is the king of digital currencies but knowledge is also needed here because we should understand the ecosystem before jumping into any space. Well dear those projects that you aforementioned Like Matic, Solana, and Ethereum are really strong ecosystem-based projects
