US lawmakers have introduced several amendments to the cryptocurrency market structure bill, including a significant proposal to ban the president and other high-ranking officials from trading digital assets. The amendments, submitted by Democratic lawmakers, aim to incorporate a "Digital Asset Ethics Act" into the bill, which would restrict "regulated personnel," such as the president, vice president, and members of Congress, from engaging in certain financial transactions involving cryptocurrencies. Additional amendments focus on preventing fraudulent activities through "digital asset self-service terminals" and delaying the implementation of new cryptocurrency legislation until at least four commissioners are appointed to the Commodity Futures Trading Commission (CFTC). Currently, the CFTC has only one commissioner, while the full complement is five, creating a point of contention among lawmakers. These proposals will be discussed in the upcoming Senate Agriculture Committee hearings.
