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..
Bitcoin is "tied" to dollars as anything else, meaning it can be sold for dollars, but it's not like dollar loses its value and Bitcoin is following. In this sense Bitcoin is "standing on its own" like you said. What can decide Bitcoin's value is its utility. If most people in the world will be using BTC for various reasons, it will be valuable for sure.
