Whatever sins Edward Snowden imagines the US committed, he is a citizen of a country that is committing genocide and atrocities. Let us not forget that Putin personally granted Snowden Russian citizenship.
No one should believe anything Snowden says. His self regard is far larger than his actual accomplishments at anything other than being a traitor to the United States.
His claims at being a whistleblower are equally empty. He exposed programs that were important to US national security and had nothing to do with US citizens.
Snowden's arguments have always been empty, so it makes perfect sense that he thinks that cryptocurrency would promote "freedom", when it in fact it promotes crime.
Russia is headed toward being a third world country. What better place for Snowden, like his predecessor Kim Philby.
