Is working on the "Ordergo" application, which involves buying and selling virtual products from international websites to earn a commission, permissible or forbidden, especially since deposits and profits are made in a digital currency (USDT) that can be withdrawn later?

It is not permissible to subscribe to the aforementioned application or work in it, because it is based on prohibited gambling. The subscriber pays money hoping to obtain more than what he paid, and this aligns with the definition of gambling: "certain loss, and probable gain." Every transaction oscillating between loss and gain is prohibited, and it is among the grave sins. Furthermore, these fictitious sales intended to inflate sales value involve deception of buyers, and deception is prohibited.
