Very interested in this one.
I agree with the commentary that the advert needs to link to a page with a clear and simple signup process.
The funding doesn't sound too unrealistic at all and I think it's worth a shot for what I think is the first venture into advertising/marketing.
I agree that many Brave users running the ads have some sort of Crypto awareness, and they could make a good target audience.
Supported and shared, good luck!
