I think Solana pumped due to some massive game projects that released too such as star atlas and many more. Their ecosystem is quite far from metamask extension but they are building their own system and other investors and whales are seeing how it got improved thats why they bought in. Its really amazing from a very low price now solana is kinda expensive. Only If I bought a lot during its early stage. Anyway thats my opinion and I think it could still grow more.
