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.
Yes, I learned about bitcoin two years ago, when the price of bitcoin was not high, but I didn't choose to buy bitcoin. I thought it was a hoax. But when my friend told me five months ago that he got a lot of money by investing in bitcoin, I was sorry. So I chose to buy bitcoin immediately. I missed the best opportunity for a lifetime.
