$DOGE #doge⚡ contract opened 75 times and held it for a day. From a floating loss of more than 10 u to a floating loss of more than 100 u, I added enough margin at the last moment when the position was about to be liquidated. The exchange rate loss of a few dollars saved the account loss of 600 to 700. This wave is very worthwhile! Sometimes holding a single order is a very necessary choice. It is about to make back the capital, hold it, and wait for the callback to make money!
