I can say, ethereum and solana. Cause both are doing good. But i think ethereum is my most favorite. There are Many reason. And ethereum is ahead in every qualities, except transaction fees. But it keep developing itself and seems wanna have its fame back. You can trust this altcoin without dount. Rather solana doing well and seems having good future. You it could down anytime which won't be wonder. So is for bnb! But for now, Ethereum is my favorite, and then i will opt solana
I want to add more coins with you some are DOT, Litecoin, Bitcoin Cash, BNB. Ethereum, Solana, BNB have performed well over the year but the price has dropped significantly since the Bitcoin halving. However, Solana Coin has been the best performer this year in my opinion. Personal judgment should prevail when investing in altcoins, although I think the coins you mentioned are very good for investing. Investing in Bitcoin as well as investing in top altcoins will yield good future profits, and I am also trying to invest in top altcoins.
