Bitcoin is a digital currency, meaning it's money controlled and stored entirely by computers spread across the internet, and this money is finding its way to more and more people and businesses around the world.
The price of a bitcoin topped $900 last week, an enormous surge in value that arrived amidst Congressional hearings where top U.S. financial regulators took a surprisingly rosy view of digital currency. Just 10 months ago, a bitcoin sold for a measly $13.
The spike was big news across the globe, from Washington to Tokyo to China, and it left many asking themselves: “What the hell is a bitcoin?” It’s a good question — not only for those with little understanding of the modern financial system and how it intersects with modern technology, but also for those steeped in the new internet-driven economy that has so quickly remade our world over the last 20 years.
Bitcoin is a digital currency, meaning it’s money controlled and stored entirely by computers spread across the internet, and this money is finding its way to more and more people and businesses around the world. But it’s much more than that, and many people — including the sharpest of internet pioneers as well as seasoned economists — are still struggling to come to terms with its many identities.
With that in mind, we give you this: an idiot’s guide to bitcoin. And there’s no shame in reading. Nowadays, as bitcoin is just beginning to show what it’s capable of, we’re all neophytes.
Bitcoin isn’t just a currency, like dollars or euros or yen. It’s a way of making payments, like PayPal or the Visa credit card network. It lets you hold money, but it also lets you spend it and trade it and move it from place to place, almost as cheaply and easily as you’d send an email.
