For me, if the majority of the people knew about bitcoin and had a proper knowledge of how to use it. If the government allow bitcoin to spread/teach the proper use in their country and help establishment to improve their technology. But first, let the people knew how it works because even establishment are accepting bitcoin as their payment,if people are afraid to deal with it, they still use paper money as a mode of payment.
In future it is expected that governments will accept bitcoin as legal currency, even those countries who have already consider bitcoin as illegal they will also turn bitcoin as legal, because bitcoin will be the future currency and its importance will continue increasing, people will use bitcoin for everything they want. Because it is more easy to use bitcoin and the most important is that it a universal currency. and is decentralized.
