DCA works well for Bitcoin, but this strategy can be approached in different ways, there are those who buy constantly regardless of the price and the market situation (as Sailor does), but there is another approach, when they buy, for example, only on corrections, or only on a bear market (which lasts for several years). I am one of those who do not buy on a bull run, you see, recently the price was 109k and now Bitcoin has corrected by 82k, this is a big difference, and this is one of the reasons why I do not buy on highs.
We'll judging from your forum registration date (2017), I would love to think you've been into Bitcoin for 8 years and have seen two full cycles and embarking in the third one, do I'll love to think that you've acquired for yourself a decent sized Bitcoin portfolio and I can understand your decision to probably focus on only dips to reach your accumulation target(, that is if you've been dedicated in your accumulation journey in your early time with Bitcoin).
Yet, any newbie, low come or nocoiner has no business waiting for the dip to acquire Bitcoin since that is a great sign of lack of vision and action on their path, they are supposed to hop in and start buying Bitcoin straight away consistently and with as much aggression as possible and try maintaining it through a whole cycle or more in order to acquire a good quantity of Bitcoin in their portfolio while also building their backup funds to serve as a guarantee that their Bitcoin portfolio remains intact and not tampered for survival and other needs.
