Unfortunately, I am not smart enough to be a coder so this is for the one who want to Build this Dapp on Sui.
Everyone likes taking a bet so predictions markets are the best for this. It can be from Football to soccer to politics to if USDT is gonna survive 2023. You can put everything on it what you can imagine and the people then putt there money where there mouth is.
I wish the builder good luck with making this one.
Here is a example:
