If we ignore the spikes above 20k and under 19k, Bitcoin was almost still in the past month.
This type of price action is unusual considering its historic volatility and a break in one direction should happen sooner rather than later.
My bias remains bearish with a valid break under 19k confirming this outlook. In such a case I expect acceleration to the downside and 15k round figure could provide soft target for bears.
On the other hand, sustained buying above 20k could lead to a rise to 25k important resistance.
