Fiat currency its a currency that a government has a control while crypto can not be manipulate and can not be created out of thin air. If people adopt a crypto currency then the fiat currency price will plummet. Its one of the reason why government impose a stricter rules in cryptocurrency.
maybe what you say is true the government always rejects and thinks negatively about the development of the crypto currency but if it can work together it will certainly make it even better for the government to monitor and monitor what will happen I think something will develop more
Actually the governments do not understand that what the benefit can give the cryptocurrencies to the governments. They do not know that the future will be of the digital currencies and people all around the world will accept Bitcoin and cryptocurrencies so if they will work from now then they will be much mature in the coming time.
