To be honest, I don't think you're in the right place. Unless you have an 'incredible' idea.

But to attract someone you have to give more information about your idea. You have to make people want to contact you. If someone is interested he will contact you. It doesn't work the opposite with someone contacting you to see how it can be interesting.

Your idea makes me think about a debit card with a cashback feature. Is that this, a card linked with a cryptos wallet? A cashback system on debit cards starts to be popular in Europe and if I'm correct it is already in The US.
