Cryptocurrency was promised for decades as the key to revolutionizing finance, but its greatest foe has always been volatility. Bitcoin, Ethereum, and other leading coins' prices can fluctuate by a few hundred dollars over several hours, so they are thrilling but perilous to investors and not suitable for regular transactions. Out of this limitation came an excellent solution: stablecoins. Unlike other cryptos, stablecoins are made in a way that they cannot change value in price. They are normally pegged to a fiat currency, such as the US dollar. Tether (USDT) and USD Coin (USDC) are the most used stablecoins today. The two cryptocurrencies have proven to be the supports of the crypto economy, acting as a connection between the traditional finance and blockchain systems.
