Only those who can keep up with the latest tech or their citizens are literate enough to use the bitcoin. I believe that bitcoin is really the answer to make use of money straight to those who are in needs. I always watched many people donating charities with millions of money but it always puzzled that it is not making a huge difference. I found out that greedy people always take a lot of it before it goes to them so blockchain is really going to end this to make a helpless community or economy to stand again.
