I think for them, they cannot buy the hash power without your initial investment. So it's like crowd sourcing in a way. In the end both you and them win. At least that's how it made sense for me after having the same thoughts as you.

Everyone wins is totally the point. There’s a little math/research to do, too, so you’re hopefully DYOR and not losing 60%
Do you have any documentation on related strategies to maximize return? This is my first experience with purchasing hash power and I'm a bit out of my element. Any information you could provide would be greatly appreciated. Thanks!
