If Ethereum still has a problem in the transaction fees, I don't think Ethereum will be the future of crypto. People don't want to use a platform or a coin or a network that requires too expensive fees. There are many chains, coins, or platforms that provide cheaper fees such as Polygon, Tron, Solana, etc. People will move to these platforms if there are no solutions from Vitalik and teams. So, the future of crypto probably move to these platforms.
