what really matters in crypto-currency world is who benefits from 1. Adoption 2. Economic Growth 3. Productivity Increases.

Ever since the Federal Reserve and their "price stability" directive, all fiat currency value increases from Economic growth and Productivity increases have been soaked up by governments (via issuance of new currency).

So, this is why I don't like ripple ... Like the Federal Reserve are with fiat currencies, the Ripple managers are set up to benefit from 1. Adoption of XRP 2. Economic Growth in XRP usage and 3. Productivity increases (which tend to deflate prices relative to an un-managed currency).

The beauty of Bitcoin and other decentralized, limited supply crypto-currencies, is that the holders and participants of economies built up around these currencies are the primary benefactors of 1. 2. and 3. mentioned above.

Besides, there will be natural price stabilizing forces in the crypto currency world such that xrp is not needed.  When the value of currencies rise too high, there will be high demand for Alternate crypto-currencies (ltc, ftc, nmc, cnc, trc, etc.)  When value of crypto currencies wanes, the less popular/functional alts will die off.   We don't need a centralized market maker trying to provide price stability ... that will come as the crypto-economy matures.
