Most people will tend to sell their currency out of fear during a market downturn. If you are holding altcoins, you should stop the loss in time to reduce the risk. It is better to lose a small amount than to lose all your funds. Be patient when holding Bitcoin, trusting that the market will rebound and the gains will continue to be reaped.
The problem of falling prices does not only occur in altcoins, but has also occurred in Bitcoin so that the problem of being patient actually has the same size for each asset being held. Altcoins can be very cheap when Bitcoin goes down, but altcoins can also recover slowly when Bitcoin starts to slowly rise again in the market. You can see at the moment that some of the altcoins are increasing in price even though the percentages are still looking a bit low.
