Only one reason, people are selling

Bearish market is because of two major reasons:

1. Christmas holiday: traders are usually inactive in the market because of off working in the Christmas holiday.

2. Whales opportunities: whales took profitable days during the bullish market after winning Donald Trump as President of US. The inactive market during the Christmas holiday is a super opportunity for whales to decrease the price of the market before going Trump into White House as President to have another opportunity of buying and promoting their profits. The bearish will continue for a few more days.
