We only need more new people to adopt Bitcoin, in this case the role of every government is very necessary to be able to legalize Bitcoin, because it will attract many people to adopt Bitcoin, so the crypto currency technology is getting bigger.
It is best we just embrace this system that satoshi has created for us without having to wait for any governments regulation, because if you are looking for government to legalize Bitcoin or regulate Bitcoin for us to get adoption, my dear, nothing of such will ever happen and we have to wake up from our sleep.
First thing we need to ask is why should government legalize a technology that you and I know that they have absolute no control over it or would be able to know any detailed transaction of its user? Without government, Bitcoin will still get its adoption, just that it will take time, which we also have to put at the back of our mind so that it can help us to be patient.
