The drop in currency price and the payback time are intuitive when put together:
Fall 10%, rise 11% to recover the capital
Fall 20%, rise 25% to recover the capital
Falling 30%, rising 43% to recover capital
Falling 40%, rising 67% to recover capital
Fall 50%, rise 100% to recover the capital
Fall 60%, rise 150% to recover the capital
Falling 70%, rising 233% to recover capital
This is why many people want to do something big, but they have been struggling to get back their money. Sometimes, the ability to admit mistakes and have the courage to stop losses is more important than making profits!
