I completely agree with the author. This is called trading. Many make good profits on this. But this requires certain knowledge and techniques. We need to understand the laws of the market.
It is important only to have access to the Internet, bank account, Visa card or Mastercard or virtual card. Everyone can anonymously own bitcoins. There is also no problem in cashing. Any more or less civilized country is suitable for this.
The government wants to regulate bitcoin because large investors want it. And big investors need regulation to protect their investments. I believe that this is a normal process. Otherwise, large investors will be afraid to enter this market.
I think that the best layout will be the adoption by regulators of positive decisions regarding bitcoin. If the authorities of the leading countries are not against bitcoin, then this will inspire confidence among the citizens of these countries.
I'm not tired of repeating that the public will believe in cryptocurrencies only if the cryptocurrency market is regulated. Otherwise, there will be no trust.
Bitcoin transactions are completely anonymous. Only address can be tracked. But the user remains unknown. The government is not in a position to change this. But they can use other means to track the bitcoin-address of a particular person.
