You have to calculate that a lot of block where POS blocks, so less total coins after POW, and foundation get's less coins to. More than halve of 35922 blocks where POS. He doesn't get 15coins per POS block. So it's hard to calculate total amount after POW if POS is active during POW.

Sum total: 36691 block, and 10.064.253 COINS generated.

If all block's where POW there should be at 36691 block, total sum of 18.345.500 COINS and 550.365 COINS in foundation.


What means, it's good to buy coins, when POW and POS is active (if you didn't mine it), and you don't wait for POW to end, because if you'r staking, you'r directly diluting total amount of coins in POW/POS phase.
Doesn't matter how many coins you have staking, important thing is you got POS blocks, so less POW blocks, less total amount after POW ends.
