| Bitcoins are mined by a decentralized network of computers that guess solutions to a mathematical puzzle. |
| Last week, Reddit announced it would accept the currency for its Gold membership, while a US start-up is taking bitcoins as payment for pizza. |
| The site functioned on a hidden area of the Internet, or the Dark Web, and only accepted payment in the form of bitcoins, the often hard-to-trace digital currency. |
| Once miners unearth 21 million coins, that's the total number of bitcoins that could possibly ever exist. |
| The police suspect that the other unaccounted for 643,000 bitcoins, were removed from customer accounts via an unknown party. |
| As prices go up, people who currently hold Bitcoins develop greater and greater expectations for the currency. |
