This is absolutely true. It is both important:
(1) be be patient to make the most of an existing bitcoin position that is in profit, and not get disturbed by short term swings.
(2) But also to use short term swings if people can be more "on the ball" and more active traders. With that, you can outperform buy and hold.
Doing some in and outs in the market frequently is as important as being patient and wait for the right time or you may say end of the world coz some people are holding them from the start and waiting patiently.
