I think all new altcoins that have been listed on CMC are good to invest in, but before that you should do further research about the altcoins to be invested, because not all new altcoins have good potential and prospects. but in my opinion a new altcoin and the one that has a great opportunity to be able to provide a lot of profit in the long term is Solana
What is your new altcoin here? because as I understand apart from bitcoin the rest on CMC are all altcoins and now they are showing over 9000 coins on it.
When it comes to investing in altcoins, if you are not doing your research and analysis, it is as if you are gambling with your money, not investing it.
Solana is no longer a new altcoin, but I have to agree with you that sol is a promising altcoin, it is a good investment and worth keeping for the long term. I would recommend you to hold it until the next bull season, it will bring you a substantial profit if you do.
