Since the price of bitcoin has down from $44,000 to $41,000, so I think a buy on dip strategy is worth considering now. I don't think such a correction will last long, especially since the halving and ETF have been the reason for the big rally. Personally, DCA isn't really needed right now, lump sum seems to be the best option.
Buying Bitcoin with a lump sum is never a bad strategy, but if you know too well that buying with a lump sum will stop you from taking care of your financial needs, don't buy with a lump sum strategy, because you think Bitcoin will never dump again, and you will see your Bitcoin even when you at a loss to solve your financial challenges. You can continue with the DCA strategy in accumulating your Bitcoin which allows you to solve your financial challenges easily while you are on your Bitcoin accumulation journey.
You're not wrong, but the point of the debate between "Buy the DIP" with a lump sum and DCA is not because of a person's financial situation, it's to find what's the more efficient/more profitable strategy. But for plebs like us who don't manage billions, I believe the difference in profit would not be that large that it wouldn't really matter.
What's probably more important is to purchase how much you can today, and front-run BlackRock, the other billionaires, and possibly also front-run nation-states.
