The XRP production schedule could be set to create 100 billion XRP over the course of 10 years at either a fixed or a decelerating rate, with the target difficulty adjusted to maintain the rate of production.
XRP is a premined altcoin tacked onto the ripple project only to pay the developers, er, board of directors.
Plus, Ripple gets guidance via CEO and a board of directors who are doing the legwork to make the system successful, instead of a bunch of neckbeards whose idea of satisfying customers is implementing "M of N signature transactions".
We're working hard to make the board of directors and CEO a lot of coins. We are not really interested in helping people secure financial transactions.
