Initiative Q is an attempt by ex-PayPal guys to create a new payment system instead of payment cards that were designed in the 1950s.
The system uses its own currency - "Q". And to get people to start using the system (when he is ready) they are allocating "Q" for free to people that sign up now. The amount drops as more people join - so better to join early.

There's nothing to lose but if this payment system becomes a world leading payment method your Qs can be worth a lot. If you missed getting bitcoin seven years ago, you wouldn't want to miss this.
