At this point the only way I can see it reach that price is by solving blockchain trilemma. Ethereum 2.0 phase zero will be launching on January 2020 but we don't know what to expect in the next couple of years. If the overall transition will be successful within 2 to 3 years reaching $2500 would be easy.
Until the end of this year I think that to reach 2500 is not possible for ethereum. although indeed there are currently so many opinions on ethereum that will increase but market analysis is more appropriate for the accuracy of ethereum prices at the end of 2019 it will decrease
