Bitcoins
How do they work?

They are:

• Popular — With over a hundred thousand users, and growing.
• Decentralized — There is no central authority governing their use.
• Limited — There is a limit of 21 million bitcoins.
• Volatile — The value of one bitcoin changes as shares and users change.
• Anonymous — You can have as many bitcoin wallets you want — they are disposable.
• Digital — No more coins weighing down your pockets again.

Onwards!
