It could happen because of ignorance or unwillingness to accept something new. Even now, I still believe some people do not believe in Bitcoin or do not want to invest in Bitcoin. Some who initially doubted or did not believe changed their views and decided to enter. Their doubts may be that they are too late, but if the situation goes back to the past, it is never too late. Now they must have enjoyed the benefits of investing in Bitcoin.
Nothing is too late, the most important thing is that those who want to start must have knowledge first.
