Stablecoins on the Market
At present, stablecoins in the cryptocurrency domain can be categorized into three types: Fiat-Collateralized stablecoins, Cryptocurrency-Collateralized stablecoins, and Algorithmic stablecoins. The distinctions among them are based on the nature of the underlying assets, collateral ratios, stablecoin issuance methods, and price stability mechanisms. 1. Fiat-Collateralized stablecoins
Fiat-Collateralized stablecoins are stablecoins issued with fiat currencies (such as USD, EUR, etc.) as collateral, such as Tether (USDT), USD Coin (USDC), and TrueUSD (TUSD). These stablecoins are usually issued and managed by centralized institutions, and maintain a collateral ratio of 1:1 in general, which means that for every stablecoin issued, one unit of legal currency needs to be pledged as collateral. 2. Cryptocurrency-collateralized stablecoins
Cryptocurrency-Collateralized stablecoins are stablecoins issued with cryptocurrencies (such as Bitcoin, Ethereum, etc.) as collateral, such as Dai, BitUSD, and sUSD. The collateral ratio of these stablecoins is relatively low, usually 1:1.5 or 1:2, which means that to issue every one of a stablecoin, 1.5 or 2 cryptocurrencies need to be pledged as collateral. 3. Algorithmic stablecoins
Algorithmic stablecoins are stablecoins that use algorithms to maintain stablecoin prices, such as Basis Cash and Frax. The price maintenance mechanism of these stablecoins is relatively complex, usually introducing elastic supply mechanisms and incentive mechanisms to adjust supply and demand and maintain price stability.
