How do you earn in Magic Craft?

Could you please elaborate on the various methods of earning in Magic Craft? I'm particularly interested in understanding how users can accumulate in-game currency, whether through completing quests, trading with other players, or engaging in any other activities. Additionally, are there any real-world monetary incentives for participating in the game, and if so, how does one go about cashing out their earnings? I'm curious about the overall earning potential and the mechanics behind it.
