$USDC The current market is fluctuating greatly with back-and-forth movements. Opening multiple contracts has resulted in stop-loss exits. It is still better to use USDC for grid trading. Just take advantage of this back-and-forth fluctuation. Additionally, there are no trading fees. I tried it yesterday, and there were profits when trading ETH in a $1 grid interval. However, if trading in USDT pairs, after deducting a $2 interval for fees, it results in a loss. Therefore, whether it is grid trading or contracts, especially high-frequency trading, everyone must know how to choose.
