Presently, should we say it's good the way bitcoin its been tied to dollars? Dollars is not backed up with any resources but to my understanding, bitcoin is a product of great energy surge. We shouldn't let bitcoin tied to dollars but bitcoin standing on its own. What could decide the durability and value of bitcoin? I have some ideas..
All I know is that when the price of the dollar goes down, the value of bitcoin will go up, and when the price of the dollar goes up in the market, the value of bitcoin will go down. As long as the movements of the two do not coincide, they are always opposed to each other.
Then the dollar is obviously under the control of the government, and Bitcoin is obviously not because it is decentralized. That's why, for 14 years, Bitcoin has not been able to be controlled by any country's government.
