Investments just require an expectation that they will rise in cost. Think baseball cards - they don't "do" anything or really have any value, but there's a pattern that rare commodities rise in cost over time. Bitcoin was engineered to stay a relatively rare commodity. Stocks are the same. The value of a stock is really only it's dividend, and many stocks don't (or can't) pay much. The cost has little to do with the value.
