I think it is possible for the bitcoin price to be $900 to 1000 in January 2017. $2000 could be possible in 2018.
I agree with that. In the short term, I mean for a few weeks, the price could drop to $550. But it will rise later.
Well, I also agree, I think it's very fast bitcoin has a price $ 2,000 in January, because most likely the price at the time of the month of January 2017 is approximately $ 900- $ 1000, even if the price of bitcoin down, but I'm pretty sure the price of bitcoin will rise to the height and stabilized in the late 2016's.
That could happen. But due to the Bitfinex hack, the price could be lower in January 2017, maybe $1000.
