What are stablecoins? Stablecoins are digital assets that are pegged to a stablecoin reserve, usually fiat currencies like the US dollar or euro. They aim to provide investors and users with a low-risk way to hold cryptocurrency, while providing institutions with a trusted store of value for their clients. Stablecoins have been around for a few years now, but they have seen a recent surge in popularity due to their potential use in the blockchain industry.
