Except that I demostrated several reasons why that is not an economic fact; and that it's long been understood that there will be institutions willing to mine zero margin or less for other economic reasons. One of which I actually do, wchich is use the heat for zone heating in winter (roughly 15% of the network hash power is "other unknown" which I would be part of) another being the competing cartels (Walmart&McDonalds versus Target & Burger King) mining for major players in competing industries, for which finance is not tehir primary business, but is already a cost center.
Ignoring Mr. Mint's concerns for a bit, I woonder, do you, or others, believe that part of the mining sincentive will also be for wealthy establishments to simply secure their wealth? E.G. if I am rich without Bitcoin, I pay large fees to my bank and security to keep my money, gold, and other wealth safe. If I am rich with bitcoin (or even if I am a wealthy corporation that has a lot of bitcoin) and want to hedge against mining attacks and help maintain the status quo, I pay to run my own mining hardware, even if it is a small portion of the whole network, and even if I have to do it at a loss.
I'm sure we discussed this point two+ years ago, and likely every year this discussion has come up since, but what are people's opinions on this, now that mining has moved from complex GPU rigs, to simple and compact ASIC appliances?
