Both are possible, it is just that since we have no way to control the events that happen around us, being too aggressive in our investment strategy can be very detrimental, if we find ourselves facing a difficult set of circumstances.
So the safest path is to build your emergency fund and only then begin to invest in bitcoin, however such an approach has an opportunity cost and you may miss buying bitcoin at an attractive price, so I can understand why you may prefer to take a hybrid approach.
I prefer to buy Bitcoin at an attractive price, namely when the price has fallen or is still in a fairly low area historically for several months. However, the investment approach as you say is also very good because everyone is required to have an emergency fund even though the fund is not used often every day. But I actually prefer to buy Bitcoin first, even in a smaller amount, rather than preparing a larger emergency fund because I like holding Bitcoin even if the amount is not that much. Because preparing an emergency fund also takes time and it could make us miss the best price on Bitcoin so that we don't have time to buy at a more attractive price.
Your strategy for buying Bitcoin are more like a some worth trading strategy, it is mostly traders that prioritized buying Bitcoin when it is relatively low or fallen (drop), in as much as buying when the price is relatively low or has fallen can be good as it gives the opportunity of buying more Bitcoin with the same amount of money used to buy lesser Bitcoin from its previous high, buying at any price point doesn't really make much of the difference if the plan is to hold for a long term, am actually wondering what could possibly be your definition of best price on Bitcoin and buying at a more attractive price? Timing the market condition can become very problematic for an investor who is still new in the market that is meant to be sizing every opportunities that shows it's self in the market in order to accumulate as much as possible up to reasonable amount of Bitcoin, with DCA strategy you are always there in the market on time without any form of timing the market condition buy making purchase of Bitcoin irrespective of the price point either weekly or monthly with as little as comfortably you can. Outside making reference to building emergency funds towards achieving our investment goal and objectives, generally emergency funds is very important in life since everyone is prone to encounter unforseen circumstances making provision for it is also very essential.
No, I disagree on what you are trying to say here that buying the deep, when the price is relatively low are meant for traders, no I disagree, to me, buying the deep is just one of the strategy of accumulating Bitcoin and getting a very large numbers of it at a very cheap price if you have the financial leverage to do so, that doesn't change the fact that the DCA accumulating strategy is the best, because you buy and accumulate Bitcoin base on how much you can afford either weekly or monthly, but you saying that if an investor decide to invest by buying only the deep looks like trading, no bro, that is what I majorly disagree on.
Lastly, the point you raised can only be valid if the person is not a long term holder or someone that sell at any slight increase in the value of Bitcoin, if not that, then I disagree on you point.
I don't know if it's auto correction working there but you might want to change
deep to
Dip...
Firstly, @Tmoonz buying the DIP is for both holders and traders but falls more to the side of holders, both are investors actually but traders will always sell execution order for a dip and buy low for a Dip I don't know if you get me clearly
However, Holders will buy dips at different entries even at the low of a Dip it doesn't necessarily need to be very large (fine if there's is a capability for it , no problem) but getting it at a lower price is what really matters..
Thus, buying the DIP is not limited to only traders infact it favours holders more than traders
