Are funds acquired from daily check-in points in a gambling and betting application, which are then converted to cryptocurrency and withdrawn, prohibited, given that no actual gambling took place?

If an application is dedicated to forbidden things, such as gambling, then it is impermissible to subscribe to it or benefit from its rewards, because that entails assisting in its dissemination and promoting its forbidden content. It is an established principle in Sharia that assisting in disobedience to Allah is forbidden, based on the Almighty's saying: "And do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty." Ibn Taymiyyah stated that whoever assists in disobeying Allah is sinful, citing the Prophet's (peace and blessings be upon him) curse on wine and ten individuals who cooperate in its production and consumption, and his prohibition against selling weapons to someone who will use them for unlawful fighting.
