I am doing a mixture of daily trading and hodling. So, I "know" in the long run I will (hopefully) have some nice profits but I am not forced to make daily trading every day. If you would focus only on day trading then you might run into the problem that you have to do something everyday even if the situation is really bad. But it is better to have the freedom to skip daily trading for some days.
Doing both thing is that nest thing do. Becasue using is apart of say trading where you need to manage your trading for you to earn. And the best way to earn thought trading is actually by holding it at the right time and with the right decision to you would probably make in order for you to earn in the future.
