Possible!
Looking at on what happened on Bitcoin with lots of Forked coins on it but still nothing beats out when it comes to its price into their parent coin or where it did forked.
It might be a much better version but still people do support on where it do originated.This is why i dont see that any upgrades or new coin will able to surpass
into that main coin.
ETH2 or something wouldnt really be just the same on where people did initially support.
You realize when I say Eth2 and Ethereum I'm talking about the same coin right? It's not two different coins. I'm talking about Ethereum. Just asking what people think the Eth2 upgrade will do for Ethereum in terms of price appreciation.
