$USDC
USDC is a stablecoin that I find quite interesting because it is backed by regularly audited dollar reserves. In trading activities, I often use $USDC as a temporary stopover when the market is sideways or too volatile. Compared to other stablecoins, USDC provides more security due to its transparency. Additionally, some platforms offer interest or rewards for holding USDC in the form of staking or lending, which makes it even more appealing. I have conducted simple arbitrage between the ETH/USDC and ETH/USDT pairs because there was a small price difference that could be exploited. In some DCA strategies, I also keep reserve funds in the form of USDC to maintain value stability before using them to enter a position. In my opinion, having a stablecoin like USDC in a portfolio is part of good risk management, especially when market conditions are uncertain.
