It seems that with every passing day, another prominent institution or business starts accepting Bitcoin for payment, Virgin Galactic being the latest example. In just a few years, Bitcoin has gone from experiment to global phenomenon.<p>I wouldn't be surprised if in coming years at least some bitcoin users start measuring their wealth in bitcoins, and therefore also evaluating exchange rates, not in terms of how many US dollars, euros, etc. they can buy with a bitcoin, but <i>the other way around</i>: what is the cost, in bitcoins, of a single dollar, euro, etc.?<p>Looking at exchange rates in this manner changes people's perspective on volatility, which is always a <i>relative</i> measure. For example, since the beginning of this year, the price of a US dollar has <i>declined by more than 98%</i>, from BTC 0.074 to just over BTC 0.001, which makes the dollar look extremely volatile!<p>--<p>PS. I'm NOT saying the dollar is extremely volatile! I'm also NOT saying that Bitcoin is more stable! What I'm saying is that if and as Bitcoin adopters start measuring their wealth in bitcoins, their perspective on what is and isn't volatile will change, as demonstrated by my example.<p>--<p>Edits: expanded second and third paragraphs; added PS.
