Tether CEO Paolo Ardoino will speak at the DC Fintech Week conference in Washington, D.C., discussing stablecoins and regulation. Tether's USDT, the largest stablecoin, holds a 71% market share of U.S. dollar-backed stablecoins, despite facing criticism over transparency and alleged criminal use. As stablecoins gain institutional importance, the U.S. lags in regulatory clarity, while Europe's Markets in Crypto-Assets regulation is set to take effect by year-end, potentially impacting Tether significantly.
