While that sounds good, you have to invest on this project alone of yours. Without monetary support from yourself, you won't get any support from other investors that sees the goal of what you're doing here.
It's a good idea that you'll make people generate any related AI things like images but, that's where it will be abused by people who sees that there's a real money in it.
This is not a sustainable idea and even you create your own altcoin about it, it's bound to fall and lose its value.
I have some anti-abuse mechanisms in mind, like making people sign up through telegram or something like that which is not easy to make "millions of accounts" (Today I saw on X that with some mail servers, you can get ChatGPT Plus for free for a long time, and I am talking like that type of abuse) and also, there must be something like this, generations give the user least amount of money and validations and suggestions give them more. Also rate limits work to some extent.
Sign up is a normal thing but asking them to do it on different platforms will just make them tired and uninterested. But whichever you think is a good idea, free to try it.
About investments, I have a friend who actually showed interest.
That's nice if there's one that's interested to invest.
It all starts with people whom trusting you with your idea but as I've said, many have I seen that they failed.
