Sellers in the market will always be there because most of the people in the market are traders so they will always carry out their activities as usual. But you also shouldn't think of them as people who trust FUD because those who are still selling have also made purchases the previous day with the aim of making a profit so they only sell when they see profits in front of their eyes. And I don't think there's anything wrong with that and anyone shouldn't make any claims that they are a believer in FUD.
Trading is indeed very profitable for those who are very skilled at trading, they choose to sell it if they see a profit for them. For me, trading is very different from investing, in investing, of course, we have to have the patience to wait for it in a few years, then we can get results, but in trading, of course, if they have seen profits, they will sell back what they have bought.
