According to Paolo Ardoino on Twitter, Tether’s USDT supply has reached 149 billion, marking a historic milestone for stablecoin market capitalization and crypto liquidity (source: @paoloardoino, May 2, 2025). This surge in circulating USDT significantly enhances liquidity across major exchanges, impacting Bitcoin, Ethereum, and altcoin trading pairs. Traders should monitor USDT inflows and outflows, as large supply increases can signal heightened market activity, increased leverage, and potential volatility on centralized and decentralized platforms.
