I am doing a project, which I am creating a stock exchange for professional athletes. Athletes are valued based on statistical performances. So depending on the amount of buyers and sellers the price of the athletes will fluctuate. The problem I am facing is what value do you receive if you purchase stock in the athlete? Is it possible to have a value? For example when you purchase stock in a company you become part owner you may be able to receive dividends, or voting rights. What value could you receive for purchasing an athlete’s statistical performances? I have read into how bitcoin is valued but I do not completely understand it?
