High gas fees, reduced popularity of DEFI, rapid decline of TVL on the chain, distrust of ETH2.0, criticism from miners, and restrictions on participants by the POS mechanism. Will the challenges of new technologies and new public chains cause ETH to decline rapidly?
Even though the gas fee of Ethereum increases with time, I do not see any reason why the DeFi project would be abandoned because more features are coming out everyday. Ethereum is a great project just like Bitcoin thay is currently having effect on the cryptocurrency market and the entire altcoin market. Ethereum will continue growing everyday and I know that later everything will be resolved.
