Internet reports that Trump's nomination of Brian Quintenz as chairman of the U.S. Commodity Futures Trading Commission (CFTC) has been postponed again, the second time his appointment process has been blocked. The CFTC is seen as a key institution that will dominate U.S. cryptocurrency regulation in the future. The vote was originally scheduled to take place on Monday, but was temporarily cancelled without an explanation. As the Senate is about to enter its August recess, any personnel appointments will be further postponed. If Quintenz is finally approved, he may face the situation that the CFTC has only one Democratic member, and outsiders are worried about whether the "one-person committee" will legally make regulatory decisions. At this time, the U.S. Congress is advancing a new bill that would give the CFTC regulation of the crypto spot market, and the delay confirmed by Quintenz may create uncertainty for the relevant legislative and regulatory framework.
