Simple answer, I believe so, it is possible to reach 500 USD
I've been using SOL and its network a lot, and I see that many new users are also using it instead of other networks, as it's cheaper, faster and easier to use
Soon they should approve the Solana ETFs, it might attract a bit more attention to the coin and the network
And I also think that it will depend on the price of BTC, if BTC continues to rise, it will pull the other coins along with it and that includes SOL.
