Many countries are trying . Because decentralization is most danger for every government because of money laundering. But they are failed due to decentralization. They can't ully control the crypto . So many exchanges are centralized who need KYC . In that case they can banned exchanges.
Yes the government is always afraid of decentralization for some reasons. But there are some things that they do say which I don’t really believe that much. OK in the case of money laundering, I might have to believe that because I’ve seen quite a few stories on people who used cryptocurrency for money laundering and they were caught and also punished for it. But in the case of government saying that cryptocurrency, especially Bitcoin, is being used for funding terrorism, that’s what I’m not really believing.
I am not believing that because they haven’t even given any proof at all to show that Bitcoin is being used for that purpose. Did they ever ask themselves this question, when there was no Bitcoin what were all these people making use of? Even before Bitcoin was created, there were people who were funding terrorism back then, so how were they able to do it? Instead of looking for excuses to give, it would be best for them to look for ways to stop those who are committing all these crimes.
