Ever seen what a tank or air-to-air missile can do to a warehouse full of asics.
Boom.
No, I haven't. I don't think anybody has, as its never happened before. Especially the "air-to-air" missile -- what do you need that for? Taking down flying mining rigs?
Nobody is destroying mining farms. You're forgetting that they are spread out all across the world. Is the U.S. also taking down China, Russia, the Czech Republic and Georgia's mining farms?
What a weird fantasy.
Besides, it would be much easier to take out the Bcash or SV networks as they are much more centralized. If Trump wants to start with them, he should feel free to do so.
