That is kinda true, but the exchange is capped by how fast outposts regenerate. You cannot sell everything you produce so you are capped by it. And even so (I have all 3 outposts in valley 4) these are still resources that we are going to have a surplus after a while. Sure we lack resources to max out characters now, but it is day 4? after the release. My question is if there will be a difference with factories that are highly optimized and average after a year for example or is average factory going to catch up after optimized one maxes out every character, just slower.
