This is the time progression of how Bitcoin has doubled it's value.

8/17/2015 - $227
12/14/2015 - $460
1/16/2017 - $920
5/15/2017 - $2,045
8/14/2017 - $4,145
11/20/2017 - $8,200
12/8/2017 - $16,400

It's usually taken 3-4 months to double its value (2016 didn't do much tho) until the last time where it doubled in 2 weeks.

Conservatively I think the Feb 2018 price should be $16,000. June 2018 should be $32,000
