So far nothing big, except for the place where i live, there are places where internet signal is so poor that I can't even visit this forum, so I can't update my wallet for few days if I am not home yet...
Let's look into this problem. People here wants the world to fully use bitcoin. How about those people with that situation? How come more in the poor country where no internet connection is really present.
So please stop pushing that bitcoin will replace banks in the future.
