To an extent governments are regulating the centralized crypto entities but to be frank, we may not like it if they have full control over regulating everything about crypto, of which we also know that they cant do that, because bitcoin in cryptocurrency cannot be regulated, even if others are, then coming back to the government regulation, not all will be in our favour if they do so, because they are going to impose inflationary charges upon every user as long as they are in charged, but this is all about decentralization and p2p which has limited them to some certain extent.
