I will not expect high prices for Ethereum until the end of the year Because I see Ethereum prices are just holding out and falling maybe $ 500 is a good deal for ethereum until end of 2020
It can be more with the progress of ethereum 2.0
The scalability is not yet updated. I think that we are still in the early stage. There was a bunch of updates that will have implemented in the future. It's just a matter of time until ether will break another resistance.
this is the beginning eth price will be in the best position, now it may still be slow but if the update 2.0 process is successful the coin price will probably fly high. and that will definitely happen in the future
