$USDC
The USDC/USDT pair is one of the least volatile in the market, as both coins are stablecoins. However, such pairs are often used for quick transitions between assets or for capital preservation during periods of heightened market instability. They can also be useful for arbitrage strategies, where a slight price difference between exchanges allows for profit from the price spread. Additionally, USDC is often used for trading with other assets, as it is supported by a well-known company and has a strong reputation in the DeFi ecosystem.
