The supply of Etherna's (ENA) US dollar-pegged stablecoin USDe has surpassed $6 billion, according to data from Etherscan. Previously, USDe overtook DAI to become the 3rd largest stablecoin in terms of supply. Stablecoins are cryptocurrencies that are pegged to the value of a fiat currency, such as the US dollar. This makes them less volatile than other cryptocurrencies, which can make them an attractive option for investors and traders. USDe is not the only stablecoin that has seen its supply increase in recent months. Several other stablecoins, such as USD Coin (USDC) and Binance USD (BUSD), have also seen their supplies increase. The growth of stablecoins is a sign of the growing interest in cryptocurrencies. Stablecoins provide a way for people to use cryptocurrencies without having to worry about the volatility of the market.
