I guess this is the human tendency that if any new and useful thing comes into the market then first place criticise it without understanding the pros and cons of it and I think the same has happened with bitcoin also , when bitcoin was introduced about a decade ago, no one has accepted it and very few who has accepted bitcoin that time are now bitcoin billionaires so we should not underestimate any thing and I think morons are the people who are still saying that bitcoin will get end one day.
