A stablecoin is a crypto token designed to track a reference value, usually 1 USD.
Types include fiat-backed, crypto-collateralized, and algorithmic designs with different failure modes.
In research workflows, Stablecoin is usually interpreted with USDT, USDC, Depeg, and DAI rather than as a standalone signal. Compare circulating float, unlock overhang, and where size can actually trade before trusting a breakout headline.
