very difficult to explain to the government because the most important thing in the minds of the government is that people who corruption will be difficult and cause the collapse of the currency price of the country because many people will use bitcoin and leave the currency of the country
For government to make bitcoin legalize is to make bitcoin centralized, but thats impossible to happen, because bitcoin is created to be decentralized in nature, if you are going to make it centralized then its creation will be nonsense. Bitcoin might fall if that thing happen. Bitcoin cant be controlled by anyone so that it cant be change.
