According to Paolo Ardoino (@paoloardoino), Tether’s USDt circulating supply has reached $153 billion as of May 29, 2025 (source: Twitter). This milestone signals a significant increase in stablecoin liquidity, supporting higher trading volumes and potentially reducing volatility across major crypto exchanges. Traders should monitor USDt’s influence on Bitcoin and altcoin price movements, as heightened supply often correlates with increased on-chain activity and improved market depth (source: Glassnode, CoinGecko).
