However upon inspection, sometimes you will realize that the government acknowledging bitcoin is not actually a good thing. First of all, the government's acknowledgement is limited to only being a speculative asset and not as a currency that can be used for official transaction. Second, their rules and regulations usually include AML and KYC which totally strips away investors' privacy and disregards decentralization. Third, governments only acknowledge bitcoin to implement high taxes which only drives investors away.
So at the end, not all kinds of acknowledgement is good.
In that context we also can't say that bitcoin is not a good thing because on the other hand they get tax benefits through exchanges that implement KYC.
This is a kind of throwing stones and hiding their hands because basically they get tax revenue from exchanges but they seem embarrassed to say it.
For official transactions it might make more sense because they need to maintain the stability of fiat currencies so implementing regulations on that could create problems because we know that bitcoin transactions are much faster and easier to do.
Everything may be related but how can regulations achieve benefits for each rule that is imposed because if not, exchanges will never be given permission to operate in their jurisdiction.
