[Repeatedly jumping between long and short] Recently, I have been shorting on rebounds and long on reverses. It is generally not recommended to hold contracts for a long time. Run when you make money. Go short when it rises too much and buy when it falls. The most important thing is to maintain a winning rate. For example, if you make 20 points each time, you will make 9100 times if you make 50 times, which is 1.2 to the 50th power. Just do 2 orders a week... I am going to make a series, 200 US dollars to challenge 500 times $BTC $ETH $SOL #美联储何时降息？ #山寨季何时到来？ #山寨现货布局如何布局
