Marshall Greenwald - CEO at Craypay joins Future Tech Podcast. CrayPay is a mobile payment app that will soon allow you to earn and use cryptocurrency tokens, called CrayCoins, at more than 50,000 retail locations across the United States. CrayPay already pays a portion of each of your purchases, but you’ll also be able to earn an additional 10% of the retail price back in CrayCoins. CrayCoins will be earned by spending within the CrayPay app, and it will be possible to use them for purchases in-store and online across 120+ national brand partners including AMC Theatres, American Eagle, Best Buy, Chili’s, Domino’s, GAP, Lowe’s, Outback Steakhouse, and Sears.
