Cruz is a nut and a moron. However, this issue is consistent with whatever tea party general philosophy he has. The libertarians have always been attracted to BTC as a way to buck the government out of their personal transactions and whatnot. If you recall the connection between libertarianism and drug legalization as well as the connect between BTC and drug deals, then you might be able to bridge the gap and see why libertarianism is loosely connected to BTC. Personally, I say "good." Why? Because, honestly, the government doesn't need to be all up in people's personal finances. Tax the corporations. Personal income tax was supposed to be a temporary tax to relieve the debt from the Civil War, and then it came back again to relieve the debt from WWI and never went away. Well, WWI ended over a hundred years ago, so, isn't it weird that we are still paying for it?! And the war on drugs was the stupidest thing since the Vietnam War, so, I'm not condoning drug use, by any means, but if people do drugs, it means they need help, not punishment. The use of BTC to purchase drugs is morally bad, but the use of BTC in general is okay with me. Anyway, I seldom agree with Cruz, and, in this case, even though I like BTC, Cruz is once again wrong in his line of thinking. Bitcoin mining uses a ton of electricity (duh), and, it uses a ton of silicon chips. If you want to be successful doing it, you need the fastest processors and the cheapest electricity. So, during one of the worst IC shortages in history and a power grid crisis, this plan makes about as much sense as using a .44 magnum to relieve a headache.
