If that person doesn't accept my answer after I explained a lot, there is no option, I think, @freemymind 🇨🇭. The mindset is various from person to person. Some people don't like to change their opinion in any situation.

For an example, two days ago I went to a pharmacy to buy medicine for my father. While he was making the medicine packs, I asked if he knew about Bitcoin. That person said me that Bitcoin is a scam. 😂

Then I explained that it is not a scam and it is a currency of freedom that is not controlled by anyone in similar words. That person argued with me that the government also refuses that as non-legal and so many other things. I explained to him about why the government doesn't like it and how Bitcoin helps to get rid of the inflation. He didn't accept it. There is a limit that we can convince people of. 😉
