The market value of Tether, the issuer of USDT, has reached a new high. CEO Paolo Ardoino said that USDT has become the most used digital dollar in the world. Since 2014, USDT has grown steadily and its current market value has exceeded 126 billion US dollars. USDT is widely used in cross-border payments, daily consumption and cryptocurrency transactions, especially in areas with severe inflation as a substitute for national currencies. Tether's business model relies on US Treasury bond returns, redemption fees and investment returns. Despite regulatory pressure, Tether's position in the stablecoin market remains strong and it may launch its own stablecoin blockchain network in the future.
