The Bitcoin Company offers a bitcoin rewards app (web- and mobile-based) that allows users to buy prepaid debit cards, gift cards, and phone top-ups, globally, while earning bitcoin back on every purchase.
Additionally, our rewards app was recently expanded to include: card-linked offers (which enable users to link their standard bank credit and debit cards within our app to then earn rewards when they shop with eligible merchants) and online offers (similar to Rakuten and Lolli).
In terms of our prepaid Visa cards - you purchase these with bitcoin and receive sats back immediately at the time of purchase. The cards are not rechargeable and aren't drawing from a bitcoin balance; rather you just buy the card value with bitcoin and earn instant rewards.
