Eth 2.0 and Ethreeum (Eth 1.0) are the same. because eth2.0 is a refinement of the first technology. and usually if a coin is experiencing good development, then the price of the coin will increase.
I don't understand what you are saying, how can you conclude that eth1.0 and eth2.0 are the same. technologically may be the same but the system developed may be different. the meaning is the same, where is there no change in the system?
Why do you think Vitalik and his fellow ethereum team members want to develop the blockchain to eth2.0, do you think they will stop at this stage, probably, the network keeps getting new implementation and upgrade, if ETH 2.0 according to it's features of low transaction fee, and others are not finally come to use, then majority of people will leave eth for bsc because of the affordable characteristics bsc has., talking about the price, yes the new development of a project affects the price positively.
I agree with you, we know that the current problem in ethereum is the high cost, so changes are made, maybe technologically it can be the same but is there no change in the system that was built. I'm sure there will be feature changes that are updated to be able to provide ethereum can move more dynamically and the speed can be faster with prices that return to the original goal.
if there is no change in what you say, then everyone can leave ethereum to look for an alternative platform that is cheaper and the transaction is fast and many have tried it, but they will not be able to move freely if ethereum can return to the beginning
