http://goo.gl/mqtyHA divide by bitcoin cap, and we get $923k per unit, little shy of 1M dollars.

And it's strictly only account for the U.S. debt.

Given that only handful ASIC sellers offering in-hand miners, most of them priced ROI to be infinity. Then it’s likely the network hash rate will reach the plateau at some point in time. It’s an indicator that miners are very reluctant to invest in mining equipment passing that point.

From this point on, the network will have some lengthy period of stability without significant hashing power increase. A government wants to destroy bitcoin, it’s easy enough to calculate the total hashing power needed to overtake 51%, and it can also execute overnight given that it’s highly possible to accumulate enough ASICs to flip on the switches at the same time. Miners won’t get enough time and resource to react.

Is this likely to happen?
