I think it's a very stupid person in the world who rejects Bitcoin, everyone is now aiming for Bitcoin, both from the lower to the upper classes, as long as we need to know that Bitcoin is currently still in the interest of all people, and still needs it at any time.
We cant push them neither. Mostly their reason are due to unstable price, fake news they heard around, capital to start with and their courage to take the risk.
They have fears in their heart and stopping them from accepting the challenge and learn from the new developments.
