What will happen is that both Solana and Ethereum will grow in terms of mainstream adoption (usage) and market price. Bitcoin will always stay on top of Ethereum for obvious reasons. Who cares, right? As long as you're able to make money with either coin, nothing else matters.
Yeah solana is great and all but the entire economy too much revolving around meme coin that if at some point the meme trend is ended and the market runs dry of trading volume solana could also be abandoned.
not denying that there are plenty of great defi in solana too even as good as ETH but the most dominating defi in solana is the one that has something to do with meme coin.
even pumpdotfun is beating ETH in term of revenue alone, that is quite the feat because pumpdotfun is just a launchpad and ethereum is a whole blockchain even 2nd highest by market cap in term of rank but got beaten by some launchpads project, however i bet solana revenue also mostly come from pumpdotfun and any other meme related defi protocols which means too depending on meme trend. this could be a flaw.
