What Is a Stablecoin?
A stablecoin is a cryptocurrency whose price is pegged to a stable asset, usually the US dollar — one USDT or USDC is meant to be worth about one dollar, unlike Bitcoin or Ether, which float freely. The peg is maintained in different ways. Fiat-backed coins (USDT, USDC) hold dollars and short-term treasuries in reserve. Crypto-backed coins (DAI) are over-collateralized with crypto. Algorithmic coins rely on mint-and-burn mechanics — the design that has failed most often, as the 2022 Terra USD collapse showed. People use stablecoins to sit out market drawdowns, move money between exchanges far cheaper than a bank wire, and earn yield without currency risk. The main risk is a depeg, when the price drifts away from $1 — even a brief 1-2% deviation is a real loss on exit.
