Let’s take when I was making my machined titanium build.
The coin gain started slow at first, but improved exponentially.
At first I was scraping to buy expensive aoe hammers, I would be mining for silver and iron to make alloys, I always end up with at least a smart stack of silver and several of gold, along side stacks of coal, and if I chose the right spot, quite a bit of diamond too.
Selling half of that would give me enough to buy tools/food for a few runs.
Also done the same for foliage/trees, which was quite profitable, as there is multiple drops on T6 which are always in demand (sap, leaves, bark).
Done that for a while, then was fortunate enough to enter into an excellent mutually beneficial deal (thanks @AeneaGames), so my costs went down and coin/mat gain went up.
Then I got into forging, and making my own tools brought the costs down again.
So went back to selling half of what I gathered, from shimmering orbs to mining loot, I would go time about from gathering mats for making forge mat to stuff I wanted for building.
And now, I don’t really focus too much on coin, though need to think a little more about it now the costs to exowarp are gonna add up.
Anytime I’m going to one, I’d be more than happy to have you warp leach!
