I would still go with a 20% founder reward like what Zcash or Zcoin has compared to a full POS ico AND the founders holding another 10% of the coins released before the software is even released. This also gives an incentive in their own currency (and not USD or Bitcoin) to keep on working.
We can argue that the 20% is a bit too high, but still better compared to the rest of the schemes.
I agree with you, too high but similar scheme to other projects reserve with incentives, which is acceptable, I am just angry about too high reserve. But this is free market, we can't control people buy or sell, I just remind those who as well think this is too high and unfair
