My biggest concern: Coin creation rate vs. Market Demand example-Pennies/CENT
If it stakes too high or too often people are going to make regular profit takings and drive the value down in a tragic "CENT death-spiral." Unfortunately once the average alt-holder makes ROI they won't care if the coin holds value, they'll just keep dumping.
To be fair, I did keep a few million CENT for the fond memories

Agreed! Let's see if the math plays out.
Currently at 3,000,000 coins, if 1/2 of those stake at 250% we would double in 1 year.
Year 2 I think we would be closer adding 5,000,000 For 11-12MM total.
Year 3+ I think the PoS diff begins to take effect and we only add 6-7MM in that year.
Year 5+ I think we are up to 25 Million and diff has taken PoS down to 100% or lower.
We can also tighten the diff adjustment so PoS goes down faster.
We need a good number of coins distributed evenly, and a fast velocity of money. I think higher inerest does these things, rather then cause an inflation spiral. But as TG says, this is an experiment, so lets see.
