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
