A California Lamborghini Dealership sells a Tesla Model S to a customer who paid for it in Bitcoin.

Maybe you've heard of Bitcoin by now, but if you haven't, here's what you need to know: it's a decentralized, electronic currency contained in the world's first completely open financial network (for a better understanding, visit this informative Washington Post article). Bitcoin can be used to buy all sorts of products through the growing list of vendors who accept the currency, and Lamborghini Newport Beach now can be added to that list.

On Wednesday, the Lamborghini dealership sold a Tesla Model S to a customer who paid for the car in Bitcoin, which were converted by an exchange service into US dollars. In an announcement on its website, Lamborghini Newport Beach says it's "fully capable of accepting Bitcoin as payment for vehicles." The electronic currency's value has increased greatly since it started catching on in early 2011, and, as of this writing, one Bitcoin is worth around $900.

If we'd only bought 100 of them for around $100 a couple of years ago...
