What is the real reason for the Bitcoin rally?

On December 12, the Nasdaq continued to rise

First breaking through 20,000 points, setting a new historical high, with an increase of over 33% this year

Currently, the Bitcoin price is 11,200

There is no market that only rises without falling; the Nasdaq will also experience a pullback after a surge. When the price trend of Bitcoin loses the support of these positive sentiments, who will be the ones to take over at the short-term high again??? $BTC
