because by holding on to overcome the good market decline and avoid losses, so by holding and patiently waiting for the price of coins to rise we can get the desired benefits
one way to avoid losses, yes of course you still survive and hold the coins you have. If you sell it when the price drops you will definitely lose, if you want to get more profit, of course you hold and patiently wait for prices to rise, often checking the market so you know when prices go up or down to avoid losses.
