How much is the campaign cost to be elected as the Secretary-general of United Nations? show me your "well known study".
The Secretary-general isn't elected but appointed:
http://www.un.org/sg/appointment.shtml....by elected officials who do ultimately have to campaign. So the answer is either a very costly sum of the campaign costs of all those that appointed them or N/A.
Or are you insinuating DPoS in the future will have appointed positions rather than elected positions?
per unit cost will shrink in ASIC, the total cost of PoW CAN NOT shrink, otherwise how do you secure the network against 51% attack? PoW expense will have to be more and more expensive as Bitcoin grows in scale.
Yes, I do expect the hash rate to increase , and electricity usage increase. This is exactly what will force decentralization and miners to need to use ASICs as products which create useful heat energy with the side effect of free PoW which can than in turn be used to subsidize the energy costs and amortize the unit costs. I don't get why you fail to understand the economics.
OMG. The appointment of secretary general is an election process! with
candidates!, how much does it cost to be a winning candidates?
Again, you are questioning reality with your imagined scenario/economics. If it was indeed profitable, it would be in mass usage by now. The REALITY is that it is NOT profitable to run a ASIC as a heater, because it CAN NOT be turned on all the time, therefore the hardware cost can not be easily recouped. It has no hope to compete against a full time mining farm. But hey if you think you are smarter than everybody else, go ahead and build your ASIC heater, and let me know of your huge product success.
