Not to be mistaken for another Jason Bourne thriller, the Edward Snowden papers show a US government/bitcoin connection. The Intercept is reporting classified documents leaked by Snowden prove that the US National Security Agency (NSA) in fact was keeping tabs on bitcoin users globally, as evidenced by a report that’s surfaced from March 2013. The timing is curious, with the ink barely dry on an executive order signed by President Trump to ban Americans from transacting with Venezuela’s Petro coin.
