Are regulations and laws possible at all when it comes to cryptocurrencies? Indeed, for every law, there must be its observance and control, and in bitcoin, this control is almost impossible. Of course, you can assign an address to any citizen, but this will not prevent a citizen from opening another hundred addresses and wallets. Therefore, with all the desire for regulation, it simply may not exist. The only thing is for those who themselves will go to submit documents for ownership of the bitcoin address;)
