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. Instead of this argument that will only make some people confused about when to enter the market, we can continue buying anyways even down to wherever the price wants to drop to before the recovery start. If we continue to argue in this direction, some people will start to form various ideas of the dip and might even decided to wait for such level to reach before they buy and this can make people miss several opportunities of getting more Bitcoin now especially when the uptrend start in an aggressive way.
Yeah you are right, dip is an opportunity to accumulate more with less price, is not something that should cause us to panic.
It is true that people can predict about Bitcoin next movement however it is always a 50 - 50 chance no body can be 100 percent sure of Bitcoin next movement so why worry yourself with it those it really matter, if you are a long term Bitcoin investor you shouldn't be disturbing yourself with such a thing, for me I don't bother my self and I don't even read about it when I see it on social media because I'm not interested, such information those not make my Bitcoin more better, information I love are information that talks about how to protect my Bitcoin investment and how to accumulate more, if as a long term Bitcoin investor I'm studying the next movement in Bitcoin then I'm not enjoying one of my privilege which is relaxing and not panic like traders do, if you are holding for 10 to 20 years those it really matter worrying yourself about Bitcoin next movement, some investors says they do that so they we no when a dip is coming so they can prepare towards it but that rubbish as an investor you need to have a reserve funds and also invest using the DCA strategy with this two things you are ready for any dip that comes in the future.
