who among you here heard bitcoin back in 2009 and 2010? I was one of the people who is very skeptical about it and I really regret it. 
I missed the best opportunity for a lifetime.
There are still people who doesn't believe to the bitcoin, I know that they will regret it in the future. We should encourage other people to use bitcoin because bitcoin will change our payment system. Most of the people should adapt digital currency for the bitcoin to become global currency.
