If a smartphone can exploit Bitcoin, then everyone has the chance to own Bitcoin. Bitcoin will become much more popular and the Bitcoin value will increase dramatically.
actually it is possible to use your smartphone as a mining tool in order to earn a bitcoin . so many websites are now offering a browser mining , cpu mining , mining via the application , etc that you can use so that you can obtain a bitcoin .
Yet , mining using a smartphone alone isnt really worth it because you can only get less profit in a longer time of work . at the end of the day , your electric charges will only go higher rather than your daily income . so think twice before you do it as a hobby .
