I wouldn't really consider the volatility of bitcoin as an advantage. Coming from the perspective that Bitcoin was created to serve as a currency, volatility seems more of a disadvantage than an advantage. Imagine paying for a product and 3 minutes later, the price pumps and you realized you paid more. Or imagine if you owned a store and you get payment for an item, 3 minutes later, the price dumps and you need to stock up again but you can't because the price dumped and your money has reduced.
