After the recent bleak market. Many people do not even understand the basic principles of Bitcoin and blockchain knowledge, so they attack Bitcoin. What kind of mental state is this?
I think the answer to this question is very simple. People simply cannot understand or find it harder to understand and accept things that they cannot touch, see or do on their own - and because they do not understand them, they are afraid of them.
And when you are afraid of something, the most normal reaction of a human being is to start talking badly about that thing and thus make other people agree with him - this gives him confidence that he is not alone.
The same was in the beginning with electricity, the telephone, the Internet and so on.
