Illiteracy is the cause of poverty. We know a cup of coffee (Starbucks) = 20 notebooks, or a school bag, or two pairs of slippers for poor children in Vietnam.
Bitcoin isn't something like a magic wand. It is not a person that will give you a help. So for me, bitcoin is definitely not gonna help poor children in an underdeveloped country because first of all, bitcoin is uncommon to them. They don't even know the existence of it. Also, they have an internet connection and even gadgets so how they gonna be involve in bitcoin. It is not also a government or a business that has a power to help them and lastly, bitcoin doesn't have the responsibility to them it is their governments and country that should have take an action.
