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 ?
They are going to try it that's for sure but it's going to be an incredible challenge, there are many people that are going to use cryptocurrencies and are going to comply with whatever the government orders them to do so that is a great advantage for them, but the ones that are holding the most bitcoin are going to be the most reluctant to comply and unless they know their identities is going to be impossible to force them to do it.
