If you are buying to hold then Solana is the top choice in altcoin investment, but for yield farming or staking then I will say Solana is not the best choice right now because we have hard bad news coming from that aspect of the Solana network as one of their top API providers just announced a closer of service and that send a vad signal for investors.
thats true seeing current circumstance of solana just doesn't seem like its gonna be rising anytime soon.
moreover it has rather been stagnant for quite some time.
the fact that some API providers are closing their service just means maybe the development in the solana blockchain isn't that great.
moreover I think it will be kept overshadowed by newer blockchain emerging though the fact that its market capitalisation still great stands still.
