Passed the exam? What now?
Once you've passed the Miner exam, you can either sell your goods independently or join/create a mining business. To start a mining business, you need to pass the Entrepreneur qualification exam. You should also consider buying a plot and setting up a store to sell your products. Find available plots for sale/lease on the StateCraft Discord. You can also sell to businesses using /find {item name} or find a shop with a minecart or enderchest.
