There are "kill switches" built into hardware and software that runs "Everything". I'm talking hospitals, rails, water plants, dams, power generating stations, grid computers....everything. Don't roll your eyes...you just saw it happen. But this run wasn't a true kill...it was more of a test. It's scary. IMO I truely think its a setup because the apparent hackers want to get paid in Bitcoins. A smoke screen to get new regulations on cryptocurrency.
