The most important thing is long-term holding, because in the short term the market cycle can go in any direction at any time, but in the long term they continue to be valuable.
Nothing good can be achieved without holding in the long term. If you do something in the short term, it becomes trading. If you do something in the short term, you cannot gain much from it. If I have done these or am still doing some things, from my own analysis, I can see that if you do something in the short term, you cannot expect anything good from it. However, some profits can be achieved but not much can be expected.
If you can maintain DCA and invest in the long term with understanding, then it is best. It is true that to get something good, you must have the mentality of holding for a long time.
