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 also regret that I learned about bitcoin a long time ago, when very few people knew about investing in bitcoin, but I thought it was a scam, so I didn't buy it. Now the price of bitcoin is hundreds of times what it used to be. I missed the best opportunity for a lifetime.
