Stablecoin is a type of digital currency that is relatively stable in value compared with other cryptocurrencies. Its value is pegged to a stable asset, such as the US dollar, the euro, gold, or other commodities. Unlike traditional cryptocurrencies, its value fluctuates within a narrow range, usually in a 1:1 relationship, making it more predictable and secure in trading and transfers.
There are usually two ways for stablecoins to work:
One is the collateralized system, in which banks that support stablecoins or users who buy stablecoins need to store a certain amount of fiat currency or other assets as collateral with the stablecoin issuer to support the value of the stablecoin.
The other is the algorithmic stablecoin, which relies on programmed rules of smart contracts to control the relationship between supply and demand of the stablecoin in order to maintain its value.
Stablecoins are gradually becoming more popular and suitable for the following scenarios:
Stabilization of investment portfolios
Currency exchange
Cross-border payments
Conversion between fiat currency and cryptocurrency
Using stablecoins in token exchanges to avoid volatility.
In summary, the concept behind stablecoins is to provide a widely accepted and used digital currency that provides a convenient and relatively stable value store while also offering the advantages of a cryptocurrency, including fast, cheap transfers, and high confidentiality.
