Neither bitcoin nor paper money has any real value, but notes have national credit support, and what if bitcoin also gets national credit? The government will lose its macro-control policy but it can also effectively eliminate inflation, two relative ratios. Is that a good result? Of course, I know that the government is very unlikely to support bitcoin, but who knows?
I would rather not want bitcoin to be supported or be adopted by a certain country to be used as means for trading purposes legally ,if it happen bitcoin will need to have a stable value and be centralized like banks.
