I think it depends on how many coins you are trying to make. When I was a brand new player and 10 or 12k coins was all I needed to get the stuff I required, the request baskets that are available were sufficient to keep me in funds. I farmed iron and copper, and made 6 or 7k coins per hour of mining. I harvested sweet and spicy beans and leaves and could make about 4 or 5k coins per hour of gathering.
At this point, more towards mid-game, the resources that I need are more expensive and complex to make, and I find that the prices on request baskets for most resources are not high enough to make it worth it for me to farm them for sale. It is more cost efficient timewise for me to just go collect the resources I need to make what I want, than it is to farm the coins that I would need to buy those resources. There are a couple resources that still give fairly good coins, such as oort and bitter beans, but everything else I would spend more time farming for coins than I would just going and getting what I need. I don’t really like hunting, so I prioritized mining, gathering, and building skill sheets over hunting. I am working on a hunter sheet and am only now getting to a point where I could farm meteors for oort to sell. Mostly I farm bitter beans for coins, and can make about 35-37k coins an hour farming those. One spot I farm is also covered in shadow orb mushrooms, and farming there I can push it to 50k coins for an hour of farming, but that is only an option once a day.
I play with a real life friend, though, and we share everything. Our workshop is shared, with open permissions for doing everything, and we split up the work. He forges all our tools, and makes food and brews. I collect all the ingredients he needs to do that. I craft all the building supplies, and farm massive quantities of rock, wood, sand and ingredients. We are sharing power coils, sharing storage, sharing spark, etc., and this cuts our costs in half pretty much. So our resource needs are split in two and we are mostly self-sufficient. Other players might find coins more necessary than we do, because they are playing by themselves or not sharing the load as much with other people. If I had to buy brews, food and tools I would be massively in the hole.
My chrysominter only has 2 power coils on it at the moment, so making coins that way is a bust. Buying the coils is out of the question pricewise, and getting the materials I need to make the coils to max it out is gonna take more than a while. No one really visits my builds, so coins from footfall is a bust. I have a shop, but even with prices listed at the very lowest on BUTT I seldom get shoppers and have pretty much given up on that whole merchant thing. There isn’t anyone to buy the stuff I can afford to sell. So the shop thing is a bust.
So…yeah. I find it difficult to generate coins. I don’t think the economy is so busted that a brand new player would be completely out of luck, but once you get towards the mid-game it gets kinda tough. If you are buying your tools, food and brews instead of forging and crafting them yourself, it might be painful. Buying building materials is mostly out of my price range, so I just make them all unless I need really small quantities.
