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.
The specified times is looking not enough for ethereum. It needs more time to reach that price. It a matter of being patient if you're in ethereum. It will give you what you want. Never worry about it.
