Basically, the release model of this coin is made in a way that is likely to generate exponential rise in the price, but then, the coin count rise is ALSO exponential and one day the coin amount will catch up with it.
With Proof Of Work finished, only 913,592 coins in existence and 20% interest per annum you're not going to see anywhere near the inflation of most other coins which generate many thousands of coins a day.
Even taking compound interest into account the slow rate at which new coins are being generated could be very easily absorbed by the market.
There have been 316.4928275 new coins generated since proof of work ended on 18th July 2014. That is less than 20 new coins a day generated by way of Proof of Stake.20% interests per annum is not equivalent to 316 coins in 16 or 17 days (I assumed daily compounding of interests).
