I think negative news has a huge effect regarding this bitcoin price dropped. Many bitcoin holders sell their bitcoin for profit and the demand is not huge enough to maintain the higher value of bitcoin. But I believe it will not last long because whales are waiting to buy in a dip.
It's not just the negative news but also the current decisions of different entities that contribute to the increase in the prices, Tesla suspending the payment of bitcoin for their cars and China banning crypto altogether are just one of the most notable decisions that are causing the prices to go down.
The China ban is probably just another propaganda and FUD to send the market down. We've been hearing that a long time ago and yet the world still shocked when this news has came out. These negative news affected the price and hit it big. IIRC, when it was on 2018-2019, those news positive or negative don't matter a lot. But because we're in a bull run, it has really affected it and that's why a lot have sold but there's sure thing on this. Many whales have sold at profit.
