The possibility of this happening is very much possible and I have not even read on the thread before reading somewhere else on how a company is planning to invest in satellites in other to ensure that bitcoin transactions are carried out without internet connection and this is very much not impossible which can equally make the use of mobile phones possible and if the penetration is going to be high, then advancement in technology needs to start looking into that direction.
yeah really agree with you thoughts brother. the way technology is advancing and the way everything is going better and better in the field of technology time by time. i think there are severe chances that it would be possible in the future.
i think the thing needed is legalization of bitcoin through super powers of the world like 'america' , 'china' and its adoption by different developing countries like india , indonasia , pakistan which has a huge number of population based of teenager or youth so, i think the more world accept it the more chances are that it will advance its technology to relief people.
