Let's say the total value of Bitcoin's in the world in 15 years is the same as the total value of Australian dollar's (AUD) in the world. Based on the rate of production it's going to take a massive amount of deflation to get there. That might make Bitcoins a good investment but it also makes them a terrible currency. (~261 billion AUD * 1.1USD/AUD / 21 million bitcoins = 13,600$/bitcoin.) All of which is beside the point, unlike banking transactions each bitcoin computer needs to be connected to the internet so you can't create a truly secure network. If the average American had 10+$ in bitcoins on their computer a significant number of them would get hacked on a regular basis and simply lose all that money. Which means for the average consumer they need to deposit that money into some sort of bank and there is no FDIC for bitcoins so when that bank is hacked all that 'money' goes up in smoke. I think we may end up with a pure digital currency sometime soon but bitcoin’s don’t really work (yet). If you want secure anonymous transactions we already have cash and several digital equivalents based on cash, but if you want stability commodity bubbles demonstrate that finite quantities does prevent bubbles and their associated crashes.
