10 percent POS rate isn't to bad, there are so many other coins out there that are like 100% or 1000%, do people really think that those coins wont flood the market with that many.
10 percent is reasonable any higher and you have a problem. If it reduces every year then you have an even better control over the price too. I personally think over time it should get towards 2% or 1 percent so that the POS mechanism still works.
agreed. I have seen dozens of coins like B3Coin EMBERCOIN etc... which has astronomically High PoS just crash and burn as soon as no new investors join them. 10% is reasonable enough to sustain this coins steady growth.
