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?
Unlikely.
I just can't imagine a cooler that will be able to lower the temperature of such a smartphone and an accumulator that would successfully withstand such a load on processor.
Anyway, technologies are developing exponentially, so we never know what new solutions will be discovered in yet a couple of years.
