I think that if there were any type of information about spying on Bitcoin, then Edward Snowden would've exposed that in his intelligence leaks. After all, he worked for both the CIA and the NSA. And isn't the NSA responsible for the creation of SHA256....

Why no mention from Snowden...? We know damn well they were watching!
Question: If Gavin's meeting with the CIA was so innocuous, why did Satoshi go underground?
Snowden is no turncoat. he's a turnturncoat. Pretending to betray his lizard masters was but a cunning ploy!
