Let's say you have ten people. Each person donates $300 and at the end of the week one person get $3000. Next week the same thing and another person in the group get $3000 and so on until all ten people in the group get their share.
This is just the basic idea.
Always Thought This Was Dumb, You Taking A 300 Hit To Get Nothing Month After Month, After It’s All Said And Done The Amount You Donated Equals The Amount You Received When It Was Your Turn, Once Everyone Gets A Turn
The Difference Between This And What The OP Posted Is That They’re Actually Investing And Getting A Return On That Investment
The Whole Point Is To Make A Profit Not Break Even lol
