If/when Eth2 launches, and if/when it's been in production long for people to be confident in its stability, I think it has a
lot of upside potential.
A working, major Proof of Stake implementation is a big deal.
It answers one of the most salient arguments against broad cryptocurrency adoption these days: the effects of PoW-based mining on the environment.
And Ethereum already has a lot going for it in terms of features (autowallets, Tornado-based private transactions, the ERC20 sea...) whether or not it can make PoS work.
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.
I'm not sure this logic holds for Ethereum;
it's already been through one high-profile fork where the "new" coin surpassed the old one. If Eth2 works, my best guess is that those on the Eth1 side who refuse to adopt the two-way peg with Eth2 will eventually be frozen out by the Ice Age; to escape that, they'd have to write a fork of their own, which will make it harder to call themselves really "Ethereum".
