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?
High fees are a problem for a long time, and that didn't stop Ethereum to make a new price record! I guess we can find a lot of criticism coming from many sides, even though I stopped using Ethereum and all Ethereum DApps because I find some other chains a lot better, I don't think we will see Ethereum rapidly declining!
New technologies will be a challenge for many/all old projects, will they adapt or they will fade away we will see, it's something that nobody can predict!
I still believe that they could solve the blockchain issue and would fix high gas fees. Criticisms will always be everywhere but I'm sure that Etherum will still stand firm. High gas fees have been their issue for such a long time but Ethereum, instead of crashing even reached more milestones and achievements.
