A few years ago, I was on the phone with a friend. He has a very high IQ and a strong learning ability, and he always values ​​my opinions.

That day, I spent several hours telling him how awesome Bitcoin was, but I failed. After thinking about it seriously, he thought it was "really a worthless scam." From then on, I stopped talking about Bitcoin to anyone around me.

Over the years, blockchain will affect the future on a larger scale. If you ignore the changes, you will fall behind.
