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..
Everything can be expressed in whatever terms that you desire, it is just that the preferred method to express this so most people understand what we mean is by the use of the US dollar, but you could express the price of bitcoin in terms of euros, gold, lambos or potatoes, and the same is true in reverse, in which we could express everything in terms of bitcoin as well, so I do not really see what your problem is with this since bitcoin is in no way tied to the dollar.
