Solana had the opportunity to take the crypto world by storm. But it blew it with the constant network outages. On top of that, FTX's collapse added more pressure against SOL's market price. I doubt it will ever rise back to $200, unless developers get their act together. They need to solve Solana's network issues so that investors could gain confidence on the project once more.
With many competitors striving to beat down Ethereum, Solana will have a hard time catching up to its rivals. At least, the project is open source. The community might decide to fork off the original chain to make an improved version of their own. I'd love to see a stable Solana-based blockchain that would render ETH obsolete. Who knows if our dreams come true someday? Just my thoughts

Yes. like the OP asked Is it advisable to invest on Solana? My. Answer. Yes. Always.
