"Unlike currency which is backed by the government and its value is determined by the economy, the government controls the amount of currency in circulation. "
Umm, yeah that's not how it works dude. Currency value is determined by the banksters that produce it and not the government puppets that borrow it from them. The government does not control the amount in circulation (well, not really) that too is in the pervue of criminal banksters, every hear of quantitative easing? The blockchain is a direct threat to establishment control over the world. Not to worry though, most of us just think it's about making more dodgy fiat currency.
