It is funny those who don't understand bitcoin are bashing it the most and when they do understand, they are turned into the most hardcore fans. 
I must say that Bitcoin is the biggest investment of the century and I think there is hardly any reason to disagree with it. The way Bitcoin is making its name in the international market, this thing is for sure that Bitcoin is going to rule the international market one day.Agree bitcoin is the biggest investment in the century those who believed in it became rich in just a span of time. Blockchain in the other hand is by far one of the best invention made.
