After 4 days of accumulations, bitcoin is creating a rising wedge pattern and this will bring a higher tendency to breakdown as it is a bearish sign. To support this, I bring up the MDAC and in the 4hr chart, December 19, it flashes bearish and it is still continuing the same direction.
If the breakdown takes place, it will bring us to the target of 22K mark.
