I couldn't agree more. Others would say that it is useless for they haven't experienced yet. Actually, they have to try first and see it for themselves and once that they've overcome it, they might see the reality that it is by far useful. For instance, my brother has been a member for almost a year using bitcoin and it is very useful to him because of financial crisis, sometimes when he has to borrow some money whenever he needs it urgently for an emergency purpose for his own family. It helps him most of the time and it saves him if the salary is delay or he's on a tight budget. I strongly believe that bitcoin is useful.
