I'm sure the government will never approve bitcoin, even though bitcoin with its blockchain technology is fairly safe for data storage systems, but we can't do anything to convince the government to approve bitcoin, because all this time the government's view of bitcoin is always negative and consider bitcoin to be a high risk in the financial system
Same with my feeling, I do not think that government will allow bitcoin to be used worldwide. They have no control over it, so they wont let it to be legalized.
