I like your project because I think your app could bring more online merchant to adopt crypto payment and bring more people to know crypto. I wish your app as a future for crypto payment and surely I will monitor your progress and maybe I will in your bounty.
Yes, the idea is certainly interesting, but technically it is a very difficult project and I think it will be implemented in the near future, but still everything will depend on the team.
But happy. that the demo will be launched in the near future. I think only after that it will be possible to draw conclusions. Let's see how this will be implemented.
