tell me please what will the profit of investors depend on? That it was possible to understand.

The price of gold is extremely important, from it, in principle, the profitability of production. And investors profit.

I think the problems with the price of gold will not be the next 10 years

I want to support you in this, I also think gold prices will be stable or grow.

here I agree with you. This is a very big profit for investors. I think everything will be fine in the future.
