Total coins: Around 2 million, with 1% inflation after 2 years
My guess is that there will be 20,000 coins mined in the 3rd year, 20,200 in the 4th year and so on.
It seems like neither of you really know for sure. This is important to know, because it determines if PTS is partially Proof of Stake or not. It also determines if it is to be held as a store of wealth (if and only if holders are encouraged to hold for 2 years) or not.
ProtoShares POW only, it's give you BitShares when they will be released, BitShares not minable at all and gives you dividents from BitShares X - distributed exchange.
After this ProtoShares will be also valuable, because will give you 10% of any DAC based on BitShares.
I think it's clear enough.
