Most of those who are nervous are short term investors who make very small investments, because big investors are investing for the long term, I think very few of them are nervous when they see the current market conditions.
Because their goal is for the long term and so they don't really care about current conditions as long as they can still buy more at the lowest price. So the only ones who are nervous are those who don't understand the risks and those who use little money because if they lose, they find it difficult to find other money to make another investment.
I don't think there are many huge investors here discussing their future. That's why I mention the topics that are closer to us. And that doesn't mean that I've invested ALL my money to crypto and now dying because of that. But for me even the amounts I've invested will bring a good addition to what I have from my job, etc.
