POS only coins ruin the coin I thin POW only and 12-20 million top total coins lifetime is a good number and have a good theme with good community support and developer that stays active in the community helps.
we can use POW and POS to make the network strongly and smoothly. Maybe it's about 90-100mil coins for both POW and POS.
I think I would leave around 80000000 pieces
There will be just the POW phase that will be that from 5000 to 10000 blocks approximately
And I think lower the number of pieces per blocks
Thank you.
