Directly from the Shareholder Letter.
We’re transitioning to a “you get Bitcoin (BTC) every time you shop” model, plus you still earn equity in iConsumer. Beginning December 23, 2017, shopping at our 1,700+ retailers by using our site, apps (or Apple or Android devices), or the iConsumer Button means you’re earning iConsumer equity (OTC: RWRDP) and now, getting Bitcoin. We’ve retired cash back.
Interesting concept! I've been using iConsumer more exclusively compared to the other popular ones (Ebates/MrRebates), as often times, it yielded more cashback.
It will be interesting to see how iConsumer develops in the next few years.
