I don't mint regularly, I have only trialled it.
The account who was making $26/day was minting 300 EGOLD (I think it was) about every 15min. We can't know what equipment he/she is using.
That is RIGHT! He/she is having a really big mining equipment and could mine same or more on other coins as well.
I managed to make it mint EGOLD, but with everything less than units=20 is pure loss.
Every transaction eats 1 nxt from account, leaving it default at 1, you will be loosing 20x more than you earning.
Interesting concept, but no real profit in it.
Out of interest, how long does it take for you to mine 300 EGOLD?
In the other thread I mentioned there is a balance to be struck between how much and how frequently you mint. Getting the most you can in the shortest time (setting 'units' low or at the minimum) isn't a good strategy. And the right 'units' setting would be different for each person depending on your settings.
EGOLD is just one of at least a dozen coins that are being minted now, it might be true that it isn't as profitable as it has become so popular. ELEMS is the other I know if but that might be in the same boat now. I think I will play around with the minter a little more...
