Although Bitcoin is a decentralized technology, it is not immune to the reach of governments. Assets need authorization to be traded and due to this situation, regulations will emerge in several countries.
Questionable assets needs government to intervene I guess, that's why bitcoin needs approval from the government, the problem with that the essence of decentralization has been stake, good thing is the actual system can go further without any changes, we do need to exchange our crypto to fiat so that's where the government will be concerned and will place every rules that will give them authority to question each profits or actual money that their people are gaining upon using this chain.
