CATDOLL : CATDOLL: Is it better to plant crops or raise livestock in the mountains?

This depends on the specific market where you are. Anyway, it doesn't matter what you do. The key is personal management.

In addition, you can observe what business your local people are doing hot.

I've observed that if people in the mountains plant more crops and the market is saturated, then you can only breed them.

If everyone makes money from breeding, you can do breeding. The market is constantly changing. It's hard to say for sure.

That's the way business works
