Scalpers, not miners. Scalpers only are able to sell at these high prices to people building industrial sized mining farms as they have a ton of start up capital and no knowledge of the msrp. I've actually talked to a millionaire family in person that was shocked to know of this. I only shared my good information with them as I wanted to help defeat scalpers who are messing things both up for gamers and independent miners. Gamers selling old card for ridiculous prices are also to blame, but who wouldn't get as much as they can?
