How to methodically determine your Bitcoin position?

Let’s say it’s safe to assume I am a bitcoiner. But I would like to take a position in it that is smart and not just DCA or buying the dip. Does anyone have any tools that they use and/or recommend to help determine what a healthy investment position in bitcoin is?

I know financial analysts and professional investors do this for stocks, so this type of methodology must be out there.

For example, the tool could take in some parameters such as age, income, risk appetite, and other factors such as fiat savings. Does anyone know of something like this available on the internet?
