The "return formula" of the currency circle:

　If the price drops by 10%, it will return to the original price if it rises by 11.1%.

　　If the price drops by 20%, it will return to the original price if it rises by 25%.

　　If the price drops by 30%, it will return to the original price if it rises by 42.8%.

　　If the price drops by 40%, it will return to the original price if it rises by 66.7%.

　　If the price drops by 50%, it will return to the original price if it rises by 100%.

　　After the loss exceeds 20%, the difficulty of returning to the original price gradually becomes exaggerated, so many investors and institutions set the loss rate of 20% as the closing line. How much did you stop loss in this wave? How much increase is needed to return to the original price?
