Yes, this is money of a new generation. Of course, they will not become the main single currency in all countries, but they will be a wonderful additional currency.
You must be dreaming, it's impossible for bitcoin or any crypto currency to become the main currency for all countries.
As long as there are people who govern this world, the centralized world will prevail over the decentralized.
Not agree with you. What's the globalization? The government can and wants to be able to manage money. Periodically, they trigger the inflation and take money from people, then they start deflation, and again Rob the people. With bitcoin this is not possible. Why is it the government?
