Unfortunately these are the very people that go around spreading whatever misconceptions they have and guess what? People believe them, they tend to be influential. But then again, why take advice from somebody who's not successful? People tend to do that, they will take advice from the uncle, from the Aunt, about investment advice (as an example) and then wonder why they are still where they are financially. Same applies to cryptocurrency stereotypes, Bitcoin has died so many times :) but it's still here.
