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 think that it would be something like that Japanese Woolwich that are attending to have the Bitcoin payment madhav integrated if the government will support that, will be the future.
