This is a meaningless "measure" a tautology. No different than saying an ounce of gold is worth an ounce of gold...Duhhh:) Do any web search you like on BTC and you will see its valuation denominated in dollars. BTC was invented to be a currency, it has already failed in this function. There are other cryptos that solved BTC's kludgyness as a means of exchange (currency) and should kryptos ever be important as currencies, that "revolutionize the world" claim, they, not BTC, are in position to do the revolutionizing. As a store of value BTC might succeed. On the other hand some malicious entity may figure out how to jam up the BTC blockchain, at which point its value will go to 0.
