If you've ever played Team Fortress 2, you know how valuable hats are. To those who haven't: yes, HATS! If a community agrees on the value of something, then that thing can become a currency, to exchange for other goods. Just like american dollar bills (or euros, yen, or any other currency), or... bitcoins. Bitcoins are an online currency worth over $200,000,000, and though they are just 1s and 0s, some think that this is the future of money. On the other hand... mo bitcoins mo problems.
