If we are daily trading then monitoring price movements is a must, we can get a lot of profit if we continue to monitor prices, and profit is something that we must get, of course it is not easy to keep observing price movements, using simple things, for example after buying and then we sell by adding profit on spot exchanges is a very good thing.
Day traders do require a good eye on any dips this will turn a profit quickly. But, for those who are making long term investments there is no need to look at the charts every day, just check if necessary and now buy again. a market crash is a sign of where to start buying again and don't panic over a price crash.
