What is the ruling on selling electronic game winnings for real money?

The buying and selling of electronic game advantages is permissible if the game itself is permissible, because these are considered additional benefits that increase enjoyment, and it is permissible to earn from them. However, a Muslim must utilize their time in what benefits them in their religion and worldly life, and beware of wasting time in idle amusement, as they will be questioned about their life and how they spent it.
