The thing is, if the high fee still unresolved after 2.0 and people slowly leaving eth, the high fee problem will solve itself and the fee will become normal again since there's no traffic. What we expect from ETH is to somehow come up with a solution to solve the scalability problem for mass adoption but whether ETH 2.0 gonna solve it or not one thing is for sure that ETH not gonna die.
How sure about this you are? Eth will not die just because of high fees.
Yeah, the most anticipated event on Eth that most investors awaited is the version 2.0. But everyone was shocked when they saw that the transaction fee was so high just like Bitcoin. My theory is this, it goes the same network with Bitcoin. Due to the continuous expansion of Defi projects, the Ethereum network has become congested which makes fee higher that can able to pay miners in order the transaction gets confirmed.
Different arguments I had heard about the Ethereum fees, IMO, a fact that Ethereum and the smart contract that most likely Defi's project used are the technological foundations that people used for the payments and money transfer in a term of Decentralized Finance.
