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?
It is difficult for that reason Ethereum is experiencing a decline going forward, the only cases involving mining critics who are dissatisfied with the results, participant restrictions have to be done for some reason, and new technologies and smart chains are things that must be faced in the challenges ahead, this is just a problem small ones that never made Ethereum lose the trust of people, because this coin has reached a very good level of utility under bitcoin, so it's hard for people to ignore them
I see no reason to be particularly concerned about the future of the ethereum network. Of course, the miners of this coin will now be unhappy that they are losing their earnings. There is a lot of controversy right now about the benefits of PoW and PoS, but apart from purely technical issues, there is also a lot of far-fetched or petty, which will rise to the rank of a serious problem, because some do not like the possible strengthening of the role of ethereum after the upgrade. There is already a little bit left and soon we will be able to see the results of the work of a large team of this coin.
