In case you hadnt noticed, hobby mining is dying. Its the big mining farms that dominate nowadays.
Point is fairly moot for other reasons though, those farms a most likely not selling on open market.
Why ? I thought pro miners are likely to dump coins to exchanges as soon as they get them to pay for the upkeep.
A.) People who cant dump without killing the price deal with people who cant buy without pumping the price.
B.) You couldnt charge a premium for
clean coins. Wouldnt want to sell the "good stuff" with all those dirty coins on market now, would you?
