I think after the 2.0 release, Ethereum price will be 300-400$ even without Bitcoin's help. I think Ethereum has enough potential to be self dependent! I am following the Vitalik and his tech team's twitter handle, they are really genius and work hard for the 2.0 release!
Should we feel the confidence of it? Not really for sure coz even there is hardfork it couldn't make a huge change.
We are already half it as of now, not that long but it takes months or years before we could make it. Now, the only hope that could make it possible is only the Bitcoin to become bullish. But unfortunately, we are still not there and we are hoping by then that this momentum will continue.
