Bear and Bullish seasons are both phases of the market that cannot be diverted, it is compulsory to experience both. Older investors with bear season experience won't see the season as storm rather full of opportunities to buy more at a lower price.
There is a logical way for holders not being driven by the storm, instead of only holding what is gathered in portfolio, acquiring more portions whenever the price dips or simply arrange a strategy to keep investing, accumulating during the bear season helps build tolerance knowing whenever the bullish seasons begins there will be share of greater profits.
