I get that there is some novelty to using an online crypto-currency. But other than the possible fun factor (which I don't expect to experience) what other reason would there be? Now, I'm not asking about Bitcoin's general merit as a currency. Personally, I believe currencies are better when regulated. But that's not what we're talking about. The question of using an unregulated, deflationary crypto-currency instead of "regular money" for most uses by a large population is a theoretical one at the moment, and will remain so for years to come. My question is about using Bitcoin casually now as a supplement to money. A vanishingly small number of vendors accept it. It is not more secure than money: I keep hearing about Bitcoins stolen from online "banks", and I wouldn't trust myself to keep it securely on my own machine. I don't intend to perform an illegal online transaction. So, why would I want to buy Bitcoin?
