The two coins
Daun for every day, DF for the market between players.
Daun
The everyday coin. You earn it by playing: harvests, hunts, villager requests, quests. You spend it on seeds, food, crafting and upgrades. You need nothing but Daun to enjoy the game.
DF
The rare coin for the market between players and the Premium shop. DF is optional: you never need it to start or to enjoy the game.
DF is an in-game currency, not an investment. Its value can go up or down. Play for fun.
