We have plenty altcoins that is good invest on, and you people invest in altcoins because of their finding in the coin they find good and believe for the project. I like this altcoins.
Cardano {ADA}
Solana { SOL}
Matic {POLYGON}
Matic, Solana and Cardano are altcoins that I also often use for day trading because I still hesitate to keep them too long in current market conditions, so I always prefer to take profit in trading even though I can't get too much profit.
