Lets say GigaVPS brokers the deals, some part of that is going to be his. If a 1.5Th unit goes for 450k, I can only imagine GigaVPS taking a good chunk of that fortune in the sale as brokerage fees.
He will get to upgrade his farm in quite a big way no matter how you look at it. But it will be on the backs of someone who is going to be paying 450k for it. Making oneself rich while making someone else poor by the same amount.
IMO, it all a pretty obvious naked scam.
It may be a poor deal on the buying end. But that does not make it a scam. Actual fraud is a required element for something to be a scam.
Where is the fraud in this deal?
