Haven't tried Cake Mobile? Well you have even more reason to try it now. Cake is offering "bug bounties." They will give you five dollars for every bug you find in the software. It is kind of half a thank you to people who are beta testing, and half an apology for bugs, but either way it is +EV for you! Want to check out Cake Mobile? Sign up for Cake here and receive 33% Rakeback! Note, this only applies to bugs found in Cake Mobile. And you have to find an actual bug in the software, you can't report an insect landing on your mobile device.
