maybe bitcoin can not be money only in some countries only. but in certain countries bitcoin can already be used like paper currency. i believe that one day bitcoin users will beat all payment systems like paypal...
I believe that when Bitcoin is used as a practical currency beyond speculators, volatility will decrease.
And Volatility in Bitcoin is something of a concern for something that is meant to be a store of value. However, the simple fact is that it was bought for speculation, and not as a store of value or a medium of exchange. The number of speculators dwarfs the number of people who buy Bitcoin for some practical use. Speculation is suitable for fast buying and selling moves, while people who really use currency depend on it.
