Just no. the fact that this conspiracy against humanity is so complex and so crazy is exactly why they have gotten it to the point that they have.
That goofy razor only applies to simple things. Hate to tell you, but when it comes to who is running the world, the crazy complex explanation is the right one.
So you feel it is more likely that the CIA is on a 9 year covert operation (plus the time it took to develop BTC) to take control of the monetary system which they already control? If the CIA created BTC what do they gain by keeping their role secret? And how come there is not a single piece of evidence linking the CIA or the US government with the creation of BTC?
There are a lot of complex things like who is running the world in which there is not simple explanation but when you start adding secret organizations and crazy conspiracies it becomes so big and complex that it makes it impossible to be true. The CIA is not an all-powerful organization, they do have access to brilliant minds and cutting edge tech but still it took them 10 years to capture Bin Laden.
