nextcolony upgrade cost is too expensive

We are upgrading every day. Uranium is already 15LVL.
I am upgrading every day like this, but the resources are still lacking.

I think people know why they invest money.
If you invest money, you can upgrade faster and start exploring faster.

I do not know what the price of the planet will be, but I want to start exploring and find the planet as soon as possible.

But the nextcolony game's purpose is to find the planet is right.?
