PCMining user here. How does the guy keep on paying us? Did he left an automatic system that keeps on sending money every week? if not, is he still manually sending money to people even if somehow everyone believes that it's a scam?
I think the payments we see each week are coming from the hardware he really does own or has a contract for with other companies. Where the whole thing fell over was when he began over selling the hardware ... That's not uncommon, it appears all cloud miners do it to a greater or lesser extent. They rely on constant incoming funds to keep the company rolling.
