But anyway, I'll explain what Bitcoin is: Bitcoin is two things, I guess. The first being a payment processing protocol much like a bank or paypal where you can transfer value (money) between different people. The reason why Bitcoin is important in this regard is that it solves what is called the 'double-spend' problem which haunts something like paypal by using a public ledger called the 'blockchain' which automatically verifies every transaction made through the network.
And bitcoins are supposed to be a type of money that is as divorced from the idea of monopoly money as possible: they are 'mined' from a decentralised network of computers; pseudonymous; and are deflationary rather than inflationary (because of the a limited supply).
