DCA with emergency fund to me sound more convincing and easy to do more than setting aside a percentage from your total income on weekly basis,  since emergency funds can also be referred to as leftover money which will be more profitable when saved in an assets that are easily converted to cash like BTC,  and from what both of you guys already mentioned,  it quite clear that emergence will be the best since in both worst cast scenario and best case scenario if you have a well planned DCA approach you will still end in a good position,  since at that point you are not  depending on your income to make your investment but rather you are buying Bitcoin from your emergence savings.


But the only side to watch out in all of this is,  you must be smart enough not to exust all your emergency saving on buying the dip and in most cases you must at least leave a small portion of the savings behind so that when you have a real life emergency,  you will have the funds to sort them out.


That way,  the pressure won't be on you bitcoin holding at once and that can allow you to bear market conditions for some time based on long term Bitcoin approach.
