The reason I say this, is because Bitcoin uses the NSA's cryptographic hashing algorithm known as SHA-256.
SHA256 is not even the important thing. if you want to start a tinfoil hat theory then at least mention the fact that the curve that bitcoin uses for its asymmetric cryptography is a curve that is created and suggested by the US government standards!

Not to mention, Bitcoin creator Satoshi Nakamoto is nowhere to be found after a decade of the cryptocurrency's inception.
what does that have to do with anything?
This means, that if Satoshi was an ordinary person instead of a government agent, he would've been found by now (even experts have been careless sometimes).
how do you know he is not found? if for example some 3 letter agency found him they are not going to publicly tell you and i about it!
One coincidence is the Bitcoin logo/symbol which greatly resembles that of the US Dollar.
that is the most tin-foily thing you said so far

mainly because you are forgetting that bitcoin logo was not designed by Satoshi.
Upon surfing the web, I've found an NSA article from 1996 which is very similar to Bitcoin's electronic cash vision in its whitepaper.
NSA is involved in all kinds of cryptography related stuff and have articles about all of them, that doesn't mean they are the creators of all of them.
If Bitcoin was truly created by the US government as an experiment, then it could be the doom of crypto and blockchain tech as we know it.
that doesn't make any sense!
The government could easily hit the "kill switch" if it owns "Satoshi's" private keys, resulting in a massive crash of Bitcoin and other crypto's price.
price crash is not equal to doom of the technology!
even if bitcoin dropped to $1 it would still survive and continue working not to mention that it won't ever do that. besides there are much easier ways of gaining a large amount of bitcoin like 1 million of it than being Satoshi and having that much!
This may sound crazy, but we shouldn't discard all the possibilities of who would've created Bitcoin in the first place. Nonetheless, what are your thoughts about this?

i am not interested in whether or not US gov. created bitcoin. i am interested in why people think that matters because it doesn't make any sense to me.
