What's your Bitcoin "elevator pitch"? Like if you only had a 30 seconds to get someone on board?

Here's mine:

1) Fully decentralized. Nobody controls it. No one can change the protocol without consensus from thousands of independent auditors around the world.

2) Unparalleled security. Wallets are unhackable. The blockchain is immutable. You can safely move a billion dollars for a nominal fee.

3) Hard capped money supply. There will never be more than 21M bitcoins (realistically less), and the rate of new supply decreases over time.

Decentralized, bombproof, digital scarcity. Come get some.
