Compared to recently hyped and grown payment solutions for crypto currency cards like PAY oder Monaco, I think I am following an uncut rough diamond. It's Proxy Card. This project seems legit, because all the devs are operating under their real names. They have strict focus on their procuct instead of making a lot of buzz for getting exchange listings very fast.
What do you think about Proxy Card?
