Oh, I got greedy again. I made about 200U from the long position at 3860 yesterday, but I didn't sell it. In the end, I made 50. I just made 300 and didn't sell it. I was too greedy and couldn't lock in the profit. In fact, most of the orders are profitable, but in the end they have to break even or even lose money. This is not a good way to play. Reflect on $ETH
