There are some who say that Bitcoin was created by the CIA. To these we give the clear answer here: NO

That was not in their mission and it does not serve any CIA or NSA purpose. Creating such a product would not be legal for the CIA or NSA due to US law regulating what they can and cannot do. Products that are developed by the CIA and NSA, e.g. software, electronic communications, computers, surveillance systems and devices, etc., are for the CIA, NSA and are sometimes shared with other government intelligence agencies. Bitcoin was developed by an underground group using the pseudonym “Satoshi Nakamoto”, not a real person. It is unclear if the developer was an individual, a group of software developers or others, but the CIA and NSA had nothing to do with it. It is true, that just before Satoshi Nakamoto “disappeared” from the online world (2011), the CIA invited one of the developers of the Bitcoin group, Gavin Andresen, to “ask” him about Bitcoin. But it is not known what has been discussed and then later Gavin was expelled from the group of developers of the Bitcoin code. So there is NO proof that the CIA is involved in this matter. Most likely, the supposed Satoshi Nakamoto, the creator of Bitcoin, has been Hal Finney, who is already dead and has taken the “deep secrets” with him, so that the CIA cannot control him.

Even then, Bitcoin code is not anymore what was in the beginning and is not controlled anymore by a single "entity", but by several developers, miners, node operators, users etc, that each one of them have its own "saying" in changing the code.

And the code is OPEN SOURCE! Anybody can review it (if they have the skills). And was already review millionths of times.
