The fear index is real, people you say? Survival is what matters to people, if situation of the economy gets worsen people won't care about holding crypto anymore, there are still millions of millions people who haven't even invested in crypto yet because of lack of regulation.
Fear is related to psychology, whoever the person is, they have an unstable psychology when the market is like today. There are some people who can stand it and have a strong psychology, but they are also backed up with strong funds. But if the funds are exhausted, then psychology will play and collapse. Survival is number one, but of course there must be a reserve even if it's only 1% of the main capital to keep things as they are now, so there won't be many losses and regrets.
Therefore, how important it is to do management before investing, to manage finances in investing and what strategies to use. Becoming an investor or trader must be smarter.
