Bitcoin is getting more bearish because it is December as many investors are waiting for December to cash out. If you look at the bitcoin price history for every bullish year you might notice December is the month with the highest bitcoin sell up. During the bitcoin bullish market, many people are investing in bitcoin and wait for December to cash out, this is not something new it is just history repeating itself.
Usually that is the trend going into winter as majority of the investors will book their profit and enjoy their vacation time, but this time around we have institutional investors as well, so anything is possible, they do not take a break like the casual investors do but there will be a time period where they will be booking their profit. It is better to prepare yourself on how the market will perform and expect the market to move in either direction in the coming months.
We can't pinpoint the culprit/s of this seemingly bearish market movement. But if you compare the price even from last year, can you say we are in the bearish mode? I don't think so. Because last year, we ended up below $30k level, so comparing its price today, which is already in the $50k price range again, we can say it is in the bullish mode as compared to last year. So yes, it depends on what time frame you are comparing here. But for me, I just be grateful that we achieve this level where I believe most old time btc holders never imagined that btc will attain this price.
