I'd say it's a great proof of concept, but not a real final product. The UX is non-existent, only supporting Stripe accounts for receiving money, and it's very restricted because not every country is allowed, since the payment intermediary is based in the US (my country, Brazil, is excluded by Stripe's rules). I would love to see this being further developed, with integration to multiple types of payments and payment processors to avoid problems like I mentioned before and other nasty ones (censorship coming from payment processors like PayPal, Stripe, VISA, MasterCard...), especially to support payments around the world, not just in a very few countries.
