When and how do you do your DCA

I recently started BTC DCA and plan on holding till another major bull because the current price is below the last bull circle's all time high.

Some analysts shared on X saying below 58k should be when to start DCA but I felt such a point of interest is too ambitious and anything from this current price should be fine if intention is to hold.

I would appreciate to hear your long term plans holding BTC if you are already on DCA like me
