Ethereum isn't going out of date it's just like the forces of supply and demand forced it's price to dump, personally I had anticipated a pump in it price just like in those days of crypto Forks, however on a long term perspective I think it price will pump massively after the successful merging of Pow to Pos, reduction in transaction gas is a welcome development invariably the high cost of transaction of it network especially ERC based projects using it network which had formally been a big issue I believed it had been addressed, I am looking forward to a high market price of ethereum in no distant future,
