Maybe add a shop system where you can buy yourself Discord and Forum roles, some of which can give you access to better giveaways and specific channels. This shop system could be put directly on the website. It would help cut down on the actual amount of money withdrawn as some people might go for those roles (and you could raise their prices pretty high) instead of frequent small withdrawals. Forum roles would be like colored usernames and stuff like that. Discord roles could give you specific colors, access to channels, custom commands, priority in music channels/private music channels, and channels where you can give access to specific users.
