Yeah no one's gonna give you money cause you have an idea for a server you've not even said anything about. You've not given any new or fresh ideas, you've just said "servers nowadays suck, and I can do it better if someone else gave me their money".
Don't listen to that, just have ranks be obtainable through gameplay, and any perks that can't be obtained for free through gameplay, must only be cosmetic.
This way you can let players have a low chance of getting a rank out of a daily chest, or take a long time to buy it with in-game currency, and you're good.
I do not recommend putting your time into this server, they @everyone with invites to those "invite for paypal money" discords and give away free things on the server that hasn't even been released yet. 3 months and little progress. Yikes.
