In some parts of the world, there are a large number of people who have no proper knowledge about Bitcoin and have been misled because of their lack of knowledge. That's why they have such a bad impression of Bitcoin. Although we cannot help everyone at once, it's just a kind of gradual process where you have to properly educate anybody you come across who has a misconception about Bitcoin. Like you said, if you ask some people about Bitcoin and many of them don't know about it, if you want to educate them, you can equally organize a Bitcoin meeting where you have to properly educate them all about Bitcoin. I did attend some seminars where I really learned a few things about Bitcoin, which got me to really give it my full attention. You can equally organize a small class for them, and if they learn well, they can equally teach others, and by so doing, the knowledge will spread gradually.
Yes, what you have said is the truth. The number of people who haven't heard about Bitcoin or don't have good knowledge about Bitcoin is bigger than the one that truly know about Bitcoin and what it means. Some people who have misconceptions about Bitcoin might have gotten the wrong ideas from people who have low ideas about Bitcoin and this is spreading wrong information about Bitcoin.
Organizing or attending a Bitcoin class is a very good idea, it will help people to know and gather good information about Bitcoin. Some people who failed to learn about Bitcoin find it so difficult sometimes when they come across things that they have never seen before they get confused although outside online, it is very hard to find a legit Bitcoin class in some society.
