Last time I talked about a method to trade volatility by simultaneously buying long and short contracts. As long as it fluctuates within a certain range, if done correctly, you can make a guaranteed profit. This time, I will discuss another method, which is to simultaneously buy options in both directions. For example, if the current price is 93,000, you can buy options for 90,000 and 96,000. By holding these, you can profit as long as the price goes too high or too low. The principle is that one direction's option will become worthless, equivalent to expiring, while the other continues to increase in value, and naturally, you will make a profit. $BTC
