Yes, in fact, combining HODL with DCA is a winning strategy for BTC, especially during periods of panic.
Saying this also would not be wrong; it depends more on one's plan whether they are using a DCA strategy or a lump sum strategy for bitcoin accumulation. As either of them can be adopted for bitcoin buying, if you are the one who has good inflow funds and have the power for consistent buying, then the DCA strategy suits you best. On the other hand, if you can buy on a consistent basis, then you can also go for the lump sum strategy for long-term holding. So, it's all about your plan.
Novice investors who are just now entering the market can be influenced by the news, leading them to be very weak hands and end up selling. In a bearish trend, the best thing to do is buy (if you have the money) to accumulate more BTC; otherwise, it's better to stay in HODL mode.
That is why, when anyone is entering the market, it is always better to do good research first so that you know where you are jumping into. Research safely those weak hands and help them to understand the trapping strategies of big hand/whales of the market. So, always researching first is the best way for your own safety in the crypto space.
