even ethereum with current market cap could hardly hold the price of $3000 just see now it has tanked to $2,900 and its not gonna be easy for ethereum to reach all time high again unless bitcoin sudden rally comes to the rescue.
solana reaching $300k means there need to be 20x gain of current market cap whereas current market cap is already $64 billion, where do the money gonna come from since even speaking frankly even ethereum that is currently price dabout $2900 even having price volatility in quite the scale right now is only having circulating supply only 1/4 of SOL circulating supply if not less.
saying that it will reach $3k maybe realistic when current market cap of crypto in general including bitcoin which amounts to $2.6 trillion could grow to $4 trillion then there's a slight chance for SOL.
currently i say that $3k is just a wishful thinking probably won't ever get to that price ever.
