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?
Since we are having an already grown Bitcoin mining expensiveness and hardness, I don't think that smartphones will be every using to mine Bitcoin, they're just not that performant.
