What if our government add tax whenever we transact fiat-crypto and vice versa, and the fund will be used for our protection(ICO,Scams,Phishings), for example the government will make a group or sector that focuses on crypto environtment. what do you think?
It's a horrible idea. Government is the problem, not the solution to problems.
The true purpose of cryptocurrencies is libertarianism and disintermediation. Big centralized government is the opposite of this.
