What is a Bitcoin?

That's the title of a live radio program I took part in this Tuesday on KCUR, Kansas City's NPR radio station. Josh Zerlan, COO of Butterfly Labs (which manufactures Bitcoin mining hardware) also took part in the segment, as did several persons who called in with questions. The program was very ably hosted by Brian Ellison.

When I first took a good look at Bitcoin about a year ago, it could claim only about 1000 registered bitcoin-accepting merchants. Today the figure is 10,000. I wouldn't be surprised if it reached 100,000 in another year.
