Stablecoins play a key role in the crypto ecosystem, as they allow users to make transactions without fear of volatility. For example, USDT or USDC are pegged to the US dollar, and therefore their price changes very little. This is very convenient for both regular users and businesses that accept crypto payments. The advantages of stablecoins include fast transfers, low fees, and the ability to avoid banking restrictions. They are also ideal for storing funds during periods of market turbulence.
