From block 7000 the reward is
nSubsidy = (44444444.0 / (pow((dDiff+2600.0)/9.0,2.0)));
if (nSubsidy > 25) nSubsidy = 55;
if (nSubsidy < 5) nSubsidy = 15;
So minimum drops to 15 HEDG, and maximum drops to 55 HEDG.
This does not seem to be the case now?
The correct answer is:
if((nHeight >= 7000 [u][b]&& dDiff > 75[/b][/u]) || nHeight >= 15000) { // GPU/ASIC difficulty calc
// 2222222/(((x+2600)/9)^2)
nSubsidy = (44444444.0 / (pow((dDiff+2600.0)/9.0,2.0)));
if (nSubsidy > 25) nSubsidy = 55;
if (nSubsidy < 5) nSubsidy = 15;
} else { // CPU mining calc
nSubsidy = (22222.0 / (pow((dDiff+51.0)/6.0,2.0)));
if (nSubsidy > 500) nSubsidy = 500;
if (nSubsidy < 25) nSubsidy = 25;
}
Since difficulty is so low, rewards stay at CPU mining levels.
Once it goes up, it drops to GPU mining levels.
Meaning, from this blocks forwards, renting huge hashes will result in very poor rewards.
This coin is a people coin, best mined with single GPU/CPU.
