if the 2.0 version will be released together in time of bitcoin Miners halving?then we may see ATH and cross the $1,500 price last january 2018.
IMO, that's not guaranteed, what if ETH 2.0 was launch last year and we know that bitcoin is not that bullish as we are expecting, I think that update would still not gonna push for ETH to rise that high. You are talking of the new ATH, the last time it reached its ATH was when Bitcoin went to $20,000, so I think we need the similar situation.
I think ETH is not that tied to BTC growth anymore. BTC is falling now but ETH remains bullish.
