There’s an alternative conspiracy theory that is very popular on some Russian websites. It starts similar to this one but then the plot twists in an entirely different direction.
An NSA employee invented the Bitcoin network, which is evident by some of the hashes they used (sounds familiar?). However, this was a planned activity sanctioned by the US government, not a rouge job. The intent was to replace dollar with bitcoin and then get rid off US national debt. As such, bitcoin will be supported by the NSA and the power of USA to eliminate competition. Twist, eh?
