$1000 ether price in January is simply speculation. But one thing I know for sure is that we will likely not see the present ether price again! I am sure the days of '100's' in price of ether is gradually coming to an end!
I think it will hit it in Feb or March, just my thought on the coin hence Dec and Jan aren't the best months for business man, they'r on vacations on these months. I'm not joking.
