Though its easy to see why governments would want to regulate the movement of digital currencies, the reality of doing so is much harder. A lot of wallets have no identification to them and rest on a server in a third party country. In the case of offline wallets in devices such as the Ledger Nano, theyre not connected to any network.so is it possible to regulate ?
Like its original nature, decentralized digital currency movements cannot be regulated by anyone including the government. But the government can do this by forcing each exchange to require every user to provide an original ID especially when they want to register.
This is why we need decentralized exchanges, governments are going to try to attack every single centralized point of failure that we create, so not only cryptocurrencies need to be decentralized, all the market needs to be decentralized as well and that includes exchanges, and while there are several decentralized exchanges there is still not one that can compete with its centralized counterparts.
