The other scenario is that if Bitcoin price goes down below 100k to 90k or 80 then we can say price has gone down significantly. In that situation it's best to take a break and hodl your Bitcoin. No need to panic because price of Bitcoin will eventually recover in the long run.
This is not a good investment accumulation practice for anyone who is building his bitcoin portfolio in his early stage. Why will you stop your bitcoin investment just because the price dipped to 90k and below. It means that you don't understand how bitcoin works. When bitcoin price dip is not the time for you to pause your bitcoin accumulation. Rather, it should be an opportunity for you to buy bitcoin cheaper. This is why you see that having reserve funds is very useful and needful as a long-term bitcoin investor, because when there is a dip, you can buy more bitcoin with your reserve funds while your regular DCA is ongoing.
When you take a break, instead of to continue with your DCA, you will lose out the opportunity of getting cheaper bitcoin for a better profit in future and your will limit the quantity of bitcoin that you should accumulate in 4-10 years and above. How long will you keep pausing your bitcoin accumulation because of a dip, it shows sign of not being committed to increasing and building your bitcoin portfolio overtime. Don't forget that the size of your bitcoin portfolio is what will determine your profit in the future.
Since you said that bitcoin price will eventually recover is the main reason to keep your bitcoin accumulation ongoing with persistent and consistent irrespective of bitcoin price and forget about what is happening in the market
