$BTC There are two primary causes for the bear market:1. Christmas holiday: Since traders are off from work over the Christmas vacation, they are usually not active in the market.2. Whale opportunities: Following Donald Trump's election as US president, the market was robust, and Whales benefited from this. The market's lack of activity over the Christmas break gives whales a great chance to cut prices before Trump takes office, which enables them to repurchase and advertise their gains. A few more days will see the continuation of the bearish trend.
