Is it permissible to earn money from selling virtual currencies (kama) or points accumulated in the game "Dofus" through playing and completing missions?

If the game is permissible, then there is no harm in selling points or virtual currency within it to upgrade the game and gain additional advantages. Therefore, it is permissible to exchange them and earn from them. However, a Muslim should utilize their time in what benefits them in their religious and worldly affairs, and be wary of wasting time in idle amusement. For they will be held accountable for their life on the Day of Judgment, and they should seize their youth, health, wealth, free time, and life before they pass away.
