OP, you can't change the world, and you can't help all people, but you can be an example for your environment.
Exactly a good point for OP.
Normal humans are influenced by what we read, see, hear, and the environment we find ourselves in, but the good thing is that humans never stop learning. If you see a person who has a negative influence about Bitcoin, you can always explain to them to better their understanding. Though, some people think that the only crypto is Bitcoin (yes!) and that's why most individuals of the public would always have a negative impression about Bitcoin because they have fallen victim to some scam projects or their friends. Scam projects that get prompted on social media have disappeared with some individuals money, and as these processes continue to take place, it will still make some people see crypto in a bad way, but Bitcoin is not really the coin that may have given them the negative impression, so when we see people like that, the good thing to do for them is make them understand better what they don't know.
