Well, this is not surprising. People who have a good wealth, can afford to invest (invest) in the project / coin without fear of losing something. This is how it happens.
You are saying this like they are just wasting their money.
They are investors, they don't invest on projects or coins just because they want to. They risk their money on these projects because they know they have the chance of earning money. They know the risk there, they are risking their money and they are not that kind of investor that just let their money up even if they lose. They invest to earn not because they want to.
