Why can the price of a coin fall during a sharp increase?

Once you notice a coin falling during a sharp rise, immediately follow these steps:

At this point, you need to check all the cryptocurrency coins on the market and make sure that there is not a massive outflow of capital from many cryptocurrencies. If there is a massive outflow of capital from many cryptocurrencies, it means that after a sharp fall there should be a correction to the previous position. If there is no massive outflow of capital, it means that at the moment of sharp growth and before it there were large players who, having seen a sufficiently long % increase on their balance sheet, decided to suddenly sell their coins and take profits and hold the coin further only taking into account the medium-term growth of this coin counting inertia for a maximum of 24 hours.
