People that are looking for conspiracies can find one everywhere. Bitcoin is conspiracy friendly anyway because we don't know the identity of Satoshi and because of other things that came to light like crypto algorithms being potentially rigged by the nsa.
So yeah - NSA designed SHA256 hash function that BitCoin is using. Strange.. Sure - hash functions might be rigged by them somehow. Im not expert on cryptographics so i dont know how they could use it against Bitcoin..
That's well known and not strange at all. It's like saying that everything that uses a Sha functions is built by the government
Rigged algorithms nevertheless might be a real issue.
