very nice and cool project.. I checked the MVP . and I can admit that I got inspired. (MVP is not completed. seems it is just a image yet) but the idea catch my mind.  but the main thing is how you will make it true..
if this become possible. then I am sure it'll be a great increment for crypto world.
we are paying a lot of fee and charges to all these third parties from which we have to pass during exchanging our cryptos to cash.
