The Bitcoin futures market is showing some interesting movements. With the upcoming U.S. CPI announcement, recent selling pressure has been quite strong. There are reports that the monthly purchase volume has turned negative, clearly indicating a shift from buyers to sellers. Just before the U.S. CPI announcement, such unstable rebounds tend to increase, and this time also seems to follow that pattern. When major macroeconomic announcements are approaching, market sentiment tends to become nervous, but looking at the consistent selling trend in futures, it's clear that speculators are also in cautious mode.
