Can you explain why you say PoS scheme from block 10k to 15k 50% then 100% then 1000% but your code doesn't show this?
int64_t GetProofOfStakeReward(int64_t nCoinAge, int64_t nFees)
{
int64_t nSubsidy = nCoinAge * COIN_YEAR_REWARD * 33 / (365 * 33 + 8);
if (fDebug && GetBoolArg("-printcreation"))
printf("GetProofOfStakeReward(): create=%s nCoinAge=%"PRId64"\n", FormatMoney(nSubsidy).c_str(), nCoinAge);
return nSubsidy + nFees;
}
