you have to know that there is an actions called cut loss to avoid big losses on your bitcoin investment. we do not need to always hold our bitcoin until the price is higher than buying price.
Cut Loss does function to avoid losses, but it is usually very often used by traders in the market, not by investors who like to invest in Bitcoin in the long term. Because if an investor holds Bitcoin by waiting for a higher price than he has ever bought before, I think that is a very reasonable thing. Because they are investors who are looking for profits in such a way, while traders whose focus is often on the market, of course, must use several features to help themselves when trading, including the Cut Loss feature that you said.
