Does anyone suspect that
Clipse and pirateat40 might have the same business model? They both sell bitcoins locally, and they both pay extra for people to mine for them. Neither of them give away much more information than that (understandably).
Hmm....

I'm pretty sure it is, although I wasn't going to call it. He's in South Africa, and Pirateat40 is in Texas, so their markets don't really overlap when selling to local people on the ground.
As to why the buyers will pay such a premium - well I still haven't figured that out.
