So this got me thinking this morning. So the creation of a Bitcoin uses the power of your GPU if I am not mistaken, maybe CPU? The more powerful the GPU or CPU the more numbers it can crunch (which I am still confused on what the calculations are being used for). So why not a phone app that can run in the background using your GPU, or CPU and slowly create one? I guess one reason would be battery life, It would really suck it down. But still I am not surprised someone has not either hidden it in an app, or made one for Bitcoin mining. I bet if you created an app right now and made sold it for $.99 you would make a killing right now.
