In your opinion, when mining technology will be available on smartphones(maybe as usual application)?
I think this does not have much sense. Maybe as soon as the processors become the same size as smartphones, but this has not yet been achieved.
I understand your point of view, all the same, nowadays we have advanced smartphones which proceed to any operation faster then 80% of computers, that's why I'm a true believer that smartphones are going to take part in the same sphere as computers in the nearest future.
Well, ok, but productivity of phone is another sphere, is not it? Mining takes place on special tech. I think if this is done on a smartphone, then we will repeat the history of Samsung from 2016.
