Let them be and if they refuse to join this market, it's their decision that will make them possibly regret in future. Just possibly because some people will never regret because they did not invest money in Bitcoin.
We should accept that we will never be able to convince everyone and that is okay. What is not okay to me is if someone refuses to use or buy bitcoin because of misinformation. If someone raises genuinely valid concerns then we can consider it and have a mature conversation.
But some are simply too close minded and they do not want to hear anyone else. They have already believed in something and would refuse to be corrected. This is what really annoys me.
That is what I faced many times as well, specially from people in the USA, and this is why I do not like it when politicians talk about bitcoin, it scares off new people. Trump likes it and shared about it, and some people who are trump supporters also shared about it, and because of that some leftists are not interested in bitcoin and think it's a right wing thing.
In reality, that is not the case and I believe we are not going to see any politician being helpful, because while their supporters will be interested, opponents will not be and that is why it sucks. In any case, when new people wants to join, it's easy to help them, when they decide to stay away, I can't be bothered to convince them, it's not my job to educate them.
