"The Bitcoin tribe is still a small one, and consists mainly of computer geeks, drug-dealers, gold bugs and libertarians. But wild fluctuations in the value of a Bitcoin, from under $20 at the start of the year to over $200 at one point this week, has won the currency wider attention. The price may yet crash to earth. But whatever happens to Bitcoin, it shows how useful a widely accepted digital currency could be," we write in a leader about Bitcoin. What do you think? Does Bitcoin (or something like it) have a future?"
