Sol has solid community, the developer is still active and what its security problem today maybe solve in the future.  So I think Solana is a good buy but be mindful of the amount you wanted to invest in to this project.  After all Crypto investment is very risky especially to ah project hat has some issue regarding its security.  Just invest what you can afford to lose. That way, even if your investment goes southward,  you won't get into a problem.
