Coinbase CEO Brian Armstrong indicates the exchange might delist Tether's USDT stablecoin if US legislation demands it. While attempts to amend US crypto laws haven't progressed, their impact on Tether could be significant. Similar challenges arose with EU's MiCA legislation.

Armstrong highlights potential US requirements for stablecoin issuers, like holding reserves in US Treasury bonds, which could affect Tether's operations. The US's evolving crypto regulatory landscape presents challenges, particularly for non-US entities.

Coinbase is also a major shareholder of Circle, adding another dimension to the competition with Tether.
