Is Solana safe long term?

Could you please shed some light on the long-term safety of Solana? I've been hearing a lot about its scalability and speed, but I'm also concerned about its stability and security. What are your thoughts on this? How does Solana stack up against other major cryptocurrencies in terms of safety? Are there any known vulnerabilities or risks that investors should be aware of? I'm really keen to understand the risks involved before making a decision to invest. Could you provide a comprehensive analysis, please?
