I'd love to see that ETH hitting to the moon, however, I don't think that ETH 2.0 is enough for that big achievement.
For ETH to rise that big again, I like to believe that it needs bitcoin to hit to the moon first, like a new ATH that would make this market crazy once again.
Definitely ETH 2.0 will not hit us in 2020 which means ETH cannot be a coin for 2020

. But when ETH will include staking feature, I guess it will find easy routes to moon for sure. Because, ETH is one of the few coin which is having a real world application and when adding an additional feature which will definitely encouraging it towards a new ATH.
