Paypie is solid and have a good team behind it. I think it is good that they are not on a big exchange without product. Let's bee patient and wait for them to deliver the product. And After we hit on big exchanges money will flow in our hands.
I agree with you, maybe this is the best opportunity to buy more PPP coin when the price still low. Paypie will begin to deliver their product on january-february 2018, based on their road map on those month they will release alpha version
