Of course, I have met outsiders with willingness to to accept new things as well. Some don't care about blockchain or disruptive technology. Their only concern is how to buy and then cash out, short-term operators. While others gradually become long-term investors by trying to understanding this industry in trading.
What would you do to your prejudiced friends?
When I talked with my friends or family about bitcoins and other crypto coins back in 2016-2017, they always said it is too risky and I will only lose all my money. They clearly didn't understand it and had a prejudice against anything new. But now since Bitcoin reached levels above 60,000 USD they changed their mind. A lot of newspapers are promoting the crypto currency market now and make it much more mainstream. It is always the same when something new comes, first people are against it because they are afraid. It just takes time to get used to the new ideas and be more open about it.
