A brother with a good relationship has been recommending SOL to me, saying that I should invest in SOL instead of ETH. It feels like SOL's wealth value is purely driven by memes, which is quite confusing. I'm thinking of starting with a small position, so I might hold both ETH and SOL. However, it's not something I truly believe in, and I'm not sure if holding onto it with a potential loss will be painful. What advantages does SOL have? Convince me.
