Purchasing multiple times every week on a consistent basis should work well for long-term holders, while those who are using DCA as a part of their trading strategy should be executing this strategy aggressively. However, the primary consideration when developing an ongoing DCA trading strategy should be portfolio assessment and risk management.
The dca strategy is not a trading strategy instead you can say that waiting for the dip before you can buy for investor who has not reach his accumulation time can be seen as a trading strategy. The dca strategy is a method of buying bitcoin consistently and regularly either every weeks or every months and hodl for long.
None of the two strategies you mentioned is a trading strategy if the investor is going long-term while adopting any of it. It is only unhealthy when a low coiner or no coiner who has discretionary income to accumulate bitcoin right away and consistently folds their hands and keeps waiting for the dip to kick off their accumulation journey, it is a sheer lack of seriousness on their path and may see them remain without much bitcoin for long or even turn just speculators in the end.
As a low coiner or no coiner, you do not have business waiting for the dip, but you should show more seriousness with your accumulation of bitcoin by starting right away at any entry point you meet it to continuously accumulate bitcoin consistently and perhaps even aggressively until you've gotten a descent stash of bitcoin and drawing closer to your accumulation target, maybe then perhaps,. Your employing only the buying the dip strategy may be justified since you are close to your target and no longer a no coiner or low coiner.
