Ethereum will definitely hit 2000 dollars but in 2 months it is definitely not possible. I would suggest you to invest in ethereum and forget it for like 6 to 9 months. When you return back you ll see 2k$ worth of ether.
I think that etherum could show its real power in the beggining of 2019 or after some months of this year, i still believe that the price of etherum could surprise every investor on this market.
