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.
I did not believe in what my friend told about bitcoin. I used to think cash was real money. But after understanding bitcoin, I regretted not believing in Bitcoin any earlier and investing in bitcoins sooner. I missed the best opportunity for a lifetime.
