Even after Ten years still Bitcoin is used by Geeks and majority of common citizens doesn't seems to use Bitcoin as a currency or even for trading purposes and I think this situation has occurred because still it is not approachable and that is because even it has all the features for a proper usability majority of people doesn't see Bitcoin as an usable currency for anyone who has basic technical knowledge which is not true but in order to change this situation and make Bitcoin more approachable to common people how its path should change in the future both technically and socially to convince it is a currency for everyone
There must be an equal distribution of infrastructure and facilities, because when all the facilities are available, it is likely that more people will understand Bitcoin. For me Bitcoin is an easy thing to use, as long as we have the willingness to be able to use new things, Bitcoin will be so easy to be accepted by many people.
