If you don't think we should be discussing bitcoin -- which is very different from any other currency out there -- simply because it hasn't reached the trading volume of Visa... I don't know what to tell you. Demonstrates pretty clearly the narrow window of information you're willing to consider.
(This on a website for hackers and startups. Pfft.)
I'll agree with you on that, but I think a good point was raised. As an inherently deflationary currency, particularly once the maximum number of bitcoins are created, wouldn't the natural thing for people believe it will eventually be incredibly valuable be to hoard them? I'm not saying that a deflationary currency cannot ever work, but with an inflationary currency, there is greater worth in spending one's money on goods or investments that will accrue worth at a greater rate than the inflation, no?
