U.S. Senator Jack Reed has introduced an amendment to the stablecoin bill that aims to ban the use of cryptocurrencies as legal tender, including prohibiting tax payments with crypto assets. This proposal was disclosed by cryptocurrency journalist Eleanor Terrett ahead of the Senate's Thursday deliberation. Additionally, Senator Elizabeth Warren has submitted over 40 amendments, including one to prevent the Federal Reserve from granting master accounts to cryptocurrency companies. In a related move, Senators Reed and Smith have jointly proposed an amendment to impose restrictions on banks' yields from stablecoins. These legislative efforts reflect growing scrutiny and regulatory measures targeting the cryptocurrency sector in the United States.
