First you must understand why people give money. Because the need a service or a solution to solve a specific problem. People are not buying random stuff from anyone. They buy from people or businesses who trust and prove that the can solve a problem. Do you have something that you can exchange with someone else and has real value? Can you repeatably find those people and sell your solution to the people who need it? This is how you will make money.
