To date, I'm not sure of any company where you can invest your money. If there is an opportunity, then I will invest only in what is practical for today. First of all, this is commercial and residential real estate, pharmacy and food business. Gold is also possible.
There is a lot of options on where you can invest your money via company. And I am remembering 2 ways. One is through the stock market where you buy and sell corporations or you can also hold a corporation's stock and wait for it to grow and another is through bonds in which they will give you a fixed interest rate depending on the period they offered it to you.
