Is it true that it will be 10% pre-mined?
Yes. It was confirmed in discord, as well as in the code.
Here's the code from main.cpp
int64_t GetProofOfWorkReward(int64_t nFees)
{
int64_t nSubsidy = 1 * COIN;
if(pindexBest->nHeight <= 1) {
nSubsidy = 7500000 * COIN;
} else if(pindexBest->nHeight <= 500000) {
nSubsidy = 100 * COIN; //50m
} else if(pindexBest->nHeight <= 1000000) {
nSubsidy = 50 * COIN; //25m
} else {
nSubsidy = 1 * COIN;
}
1st block mined by devs = 7.5m
There's been shady stuff said in the discord chat which is making most skeptical of this coin.
