my mineral bar is 50000 and i get 7423ph so my bar fills up in 7 hrs, i normally get between 1.7 and 2 bil, but i got about the same amount of money b4 i colonized more planets a few days ago, what can i do so i earn more money every time i fill my bar.
thanks in advance

As you gain rank, the weighted distribution of mineral points shifts toward the Kurenite and Aidonium, which will make a huge difference in the average value per MP that you are getting. I am not certain where this shift ends, but I will put forth a guess of Rank 600.

Rank 600 sounds about right. Another way to make more money though is thorugh artis. If you have extra time to spend online high ranking players are allways looking for smaller ranking players to spend the time to gather a lot of the arti's they need. So if you can get in with a high ranking player or two and buy cheap and sell for more to them it is a great way to make a profit. If you want me to explain more just send a PM to me and when I get on later I will answer what I can.

This one depends on whether you wish to gamble or not, I think.

Minerals will give you a guaranteed income, so you know you'll get it.

Artis can provide a much higher income ( A TM can sell in the trade groups for roughly 300 KU, possibly more, for example. ) though it is a hit or miss whether you'll get the items. you also have to save them up for a while and sell in bulk to really get any buyers.

You can also funnel research points into money once you get about 45 - 50 million research done, though I am undecided if the return ratio is that good. ( I think it is comparable to the mineral return, but I haven't really taken the time to look at it as of yet. )

You can also hunt NPCs for items to scrap down into CTP, which you can then sell for a decent amount of money.

Also work on improving your planets as much as possible to bring the resources up, as you can easily get a lot of them to over 600 an hour, often times into over 1000 or more an hour, though that will take work.
