Thank God I never lost

A question for those with experience. I am new to the field of currencies, but I have learned a lot and I still have a lot to learn. Thank God, my losses are almost negligible and my wallet is full of currencies. My question is: Is it reasonable for currencies to fall in this way and we buy them and then they rise? Will they make us profit easily? Or will currencies return to their price before November and we have to wait years for them to rise? What do you think?
