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

the whole point of investing is to ROI. I don't think people invest to lose money. Supply and demand will determine a coins value, that is price discovery.
I have already sold large blocks of HBN at around 30000 satoshi and the market has held. Price will find natural support and rebound from it. For every seller there is a buyer and you can't expect people to just buy CAP, PoS mine and never sell. Markets only work if there is buying and selling.
Also the stake time prevents people from what you call "dumping". Look at TEKcoin. People would think that TEK would just dump into nothing but wait, if you want to earn that 40% interest you need to hold for 30+ days.
I understand peoples concern about CENT but that was an outlier example. The inflation was out of control due to lack due diligence with the code. We are older and wiser now and I think that with strong developers a situation like CENT can and will be avoided.
