Bitcoin could be useful in allowing direct transfers from user to user but for such a feature to be utilized there would need to be basic infrastructure like electricity and internet. If third world countries start having those then there could be a leapfrog to bitcoin.
I agree. Bitcoin must be more accessible to people of any kind. It must add some feature that can be convenient to the users. Bitcoin community must also continue to promote himself so that it can be more informative to more people worldwide. This way those people who have no idea about bitcoin will give some attention and interest to this and become a part of the community
