In Bitcoin investment there's no such words as "impossibilities". Market rise and fall daily likewise bitcoin. Some things that people don't understand is that the principles of bitcoin innovation cannot allow bitcoin go down below some certain prices. As it stands now, it is not very realistic to start imagining bitcoin at below 70k which is already a good landmark compared to the price of bitcoin in June last year.
I agree with almost everything you said but the aspect of saying it is not very realistic to imagine Bitcoin fall below $70k which is a lie. As far as Bitcoin is a volatile asset we can't imagine the limit it will dip and it fall. Bitcoin has once reached an explicit ballpark of $69k ATH in 2021 and fall even to $15k is about %75 dip before it regaind. So price is too por to think of when it comes to Bitcoin dip because it may even dip below $70k if market permit it's. The unrealistic price we may not think of Bitcoin going back is like $40k below.
Why must we argue about the extent of the dip when we know that none of us control the market movement? I think this argument is a big distraction from the bigger picture which is to buy as much Bitcoin as we can taking advantage of every opportunity the market offer us in the form of dips.
Ups and down in the market is normal. But if someone deviates from the normal sense due to the fall, then of course his opportunity to buy Bitcoin may be reduced. Since no one can control the market, it is necessary to take advantage of it when one gets the opportunity. If you can invest regularly by doing DCA without thinking about buying Bitcoin at a specific price, then the average price for buying Bitcoin is low, which is a big opportunity for the investor. In most cases, the picture seen in the market is that some investors wait for a specific price, but it is uncertain whether Bitcoin will reach that price or not. As a result, an investor's Bitcoin investment will be delayed, but when the market recovers more, that investor will have to buy Bitcoin at a higher price. Therefore, instead of wasting time arguing unnecessarily, you should utilize the current market opportunity through DCA.
