A stablecoin is a type of cryptocurrency designed to maintain a stable value by pegging it to a reserve of assets, usually fiat currencies like the US dollar or commodities like gold. This stability aims to reduce the price volatility commonly associated with traditional cryptocurrencies.There are several types of stablecoins. Fiat-collateralized stablecoins are backed by reserves of fiat currency, where each coin is supported by a specific amount held in a bank or other trusted institution. Crypto-collateralized stablecoins use other cryptocurrencies as collateral, often over-collateralized to absorb price fluctuations. Algorithmic stablecoins, on the other hand, use algorithms to control the supply of tokens in response to demand, attempting to keep the price stable without direct backing by physical assets. Stablecoins serve various purposes, such as providing liquidity for trading, enabling easier transactions, and acting as a safeguard against market volatility. Their stability makes them appealing for users who want the benefits of digital currency without the unpredictable price swings.
