You can be applying the DCA method will keeping small part of your discretionary income for aggressive accumulation should there be a dip. So while waiting for the dip, you are already buying and holding and will not miss out on the market no matter what happens.
I don’t think what you’re suggesting is a good practice, it’s wrong to wait or plan for the dip when you’re a newbie or still in mid level in your accumulation goal. The only people who can afford to plan for the dip are those who are close to their over accumulation stage and those who have achieved that. While you’re keeping money aside for the dip you’re actually missing out on the opportunity to add more bitcoin to your portfolio, if your weekly DCA is $80 and you’re keeping $20 aside for when dip will happen and $80 gets you 0.8 BTC weekly, imagine if the dip never happens and price goes to an ATH now you’ve missed out on having atleast 1BTC weekly for the past months of your investment.
The best practice is to CONSISTENTLY follow up your DCA with the discretionary money available to you even when dip comes you’ll still be able to accumulate more buying at a discount.
