I think that when the lightning network technology will be fully implemented and operating perfectly, bitcoin will rock and mass adoption will be just around the corner.
do you think that Bitcoin will be used as a means of payment for all mankind? And what about the old people and children who will be very hard to use Bitcoin because of the lack of certain knowledge and capabilities?
actually bitcoin development is in their own community whether they still want to use bitcoin or not? because bitcoin is dependent of interest and can be worthless at any time
