[Idea] Cryptocurrency that rewards users for transacting (like cashback for creditcards) – thoughts?

Dear community,

I have an idea for a cryptocurrency that I was hoping to get feedback/thoughts from you folks.

Idea's very simple: cryptocurrency that rewards users for transacting in it (and thus incentivizes use/adoption of itself).
Similar concept in traditional finance – cashback and rewards on credit cards – has been widely adopted by most, if not all, card brands.

We have made a Proof of Concept – it's functional, here's a diagram that summarizes idea and adds some details on how it works.

Vincentiv – PoC of cryptocurrency that rewards users transacting in it.

More details are available on website – there's a working testnet and blockchain explorer that you can use to see it in action.

Questions for the community:

– Thoughts / feedback on the idea?
– Would you consider using such crypto should it become available on exchanges?
– If you'd like to participate as a developer or investor – please reach out directly.
