While I was marketing on the one hand, this question came to my mind. And I found a quick solution, and I wanted to share it.

If you borrow money from a friend at the beginning of the year, if you use the money to buy gold, at the end of the year, you can give it back as soon as you multiply the money, and continue this system with the multiplied money.

I think it will work on a plane where gold is always increasing. This logic can be called making money out of nothing.

It is not investment advice.
