it is why i propose both:
I propose cloudmining and "real mining"

let us suppose that you are a very little miner.
So little that you never reach minimum payout or you will have huge withdrawal fees.
it is why I propose the comining.

And of course nothing to see with ponzi sheme.

You mine 10000 satoshi... send you 10000 satoshi.
You ask to invest your mining in my cloudmining...I do.
It is a win-win system...
of course the co-mining is not possible for 100 people...
It is juste a ...private service.
