A stablecoin is a type of cryptocurrency built to maintain a stable price, most commonly pegged one-to-one with a traditional currency such as the US dollar. This makes it useful as a way to hold value inside the crypto ecosystem without being exposed to the price swings of assets like Bitcoin or Ethereum.
Stablecoins generally fall into a few categories. Some are backed by cash and cash-equivalent reserves held by the issuing company. Others are backed by other cryptocurrencies held in reserve, with extra collateral to absorb price swings. A smaller group relies on algorithms rather than reserves to try to maintain the peg, an approach that has proven riskier in practice.
Traders commonly use stablecoins to move funds between exchanges, to sit on the sidelines during volatile periods, or as the trading pair when buying other cryptocurrencies.
Frequently Asked Questions
Are stablecoins completely risk-free?
No. Their stability depends on the quality and transparency of their reserves or the soundness of their underlying mechanism. Some stablecoins have lost their peg in the past, especially algorithmic ones.
Why would someone use a stablecoin instead of just holding regular dollars?
Stablecoins let you stay inside the crypto ecosystem, move value quickly between exchanges or wallets, and access services like lending without converting back to a traditional bank account each time.
