最新报道:Stablecoins are cryptocurrencies designed to maintain a stable value by pegging to assets like fiat currencies or commodities. Unlike volatile cryptos such as Bitcoin, stablecoins aim to offer price stability, making them useful for payments, remittances, and hedging. Major types include fiat-collateralized (e.g., USDT, USDC), crypto-collateralized (e.g., DAI), and algorithmic stablecoins (e.g., failed TerraUSD). Fiat-backed stablecoins hold reserves in bank accounts, while crypto-backed ones use overcollateralization to absorb price swings. Algorithmic stablecoins rely on smart contracts to adjust supply dynamically. Regulators are scrutinizing stablecoins due to risks like reserve transparency and systemic financial impact, especially after Terra's collapse. Their adoption grows in DeFi, cross-border transactions, and as inflation hedges in unstable economies.
