Bitcoin dropped below $77,000 on September 10, extending its decline from the $80,000 region amid stronger US inflation data, rising Treasury yields, and significant leveraged liquidations across the cryptocurrency market. The latest retreat began after US producer price index (PPI) data showed an annual increase of 5.4% for August. In response, traders sharply raised expectations for another Federal Reserve rate hike at the next meeting. Reuters estimated the probability of a rate increase at about 70%, up from 65% before the inflation report was published.
