When we can see a chance to buy the coin when it's drop, then that will be a good decision. We can prepare by buying the coin and then we can hope that it will increase later. That is why we need to select the potential coin in the market because we see there are too many coins that could be one of the profitable coins in the future. Buying the coin in the dip will be a great way for us to get the coin at a low price, so we don't have to worry if the price does not increase for a long time.
