I have not come across such a strong ignorance, basically, if you ask people about cryptocurrency, they will answer that they only know Bitcoin. Nobody really knows about altcoins. But I'm sure this will change soon, possibly as early as 2021.
It is not certain that the mindset will change in 2021, as long as there is no education from the community or seminars that discuss cryptocurrency that achievement will never come. If that's all there is I think it will be faster to adapt to learn about bitcoin and altcoins.
It will be a lot faster if there are a lot of platforms or stores that will be using and accepting it. Seminars are not that effective if people are not actually seeing what it can do, and usually people are skeptical to join these kind of seminar as we all know, they think bitcoin as a scam. As more accepts it, the more they will be pushed to use it.
