As we all know that smartphones are just like computer nowadays that has strong storage capacity and processor. This I think could be enable to mine bitcoin and this is what I am waiting for if there are any smartphones company that would offer their smartphones for bitcoin mining or even as a smartphone that works as digital hardware wallet for bitcoin and other crypto. I am waiting for it to happen. Do you think that it will happen?
Even though smartphone now days have almost same spec like computer, computer is still better from it, i don't think this is good idea to make phone for mining tools, because everyone use their phone for communication or killing time playing some games, not for mining and i think it will use much battery and make phone run out of battery much faster. So it's better use your computer to do mining than smartphone, charging while you using your smartphone could harm battery.
