Very likely that we will see Bitcoin moves up and down in a channel for its accumulation. It can have a last dump to about $15,000 and we will see the end of accumulation. After accumulation, we will see a break out that starts another bull run for Bitcoin.
I think in the 2 weeks perspective both ranges 17.5-20 and 20-22.5 are the most probable. With odds >4.0 I will bet on them.
I really do not think it will go below 17.5, even if it is today's the most popular range.
