I've been into blockchain since 2013 and trust me, it was way harder to convince people that this is a type of technology that has potential to change how we do things in our daily lives. Not even the financial aspect of it, just the blockchain tech itself can improve many industries and eliminate middle man in those industries and allow people to do business with each other directly. Back in 2013 crypto was perceived as something that was used by criminals and no banks or financial institutions took it seriously. We made a lot of progress since then.
I think it's impossible to change it overnight or even within a year. It has to grow on people just like internet did. If you think about it, 15 years ago majority didn't have email accounts, didn't buy anything online and it wasn't the prioritized media outlet. Now, even my grandma who is over 80 has an account on facebook!
This man is a legend!
