I doubt that long term holders pray that the dip last much longer. You are out of touch with reality.
Persons who are new to investing into bitcoin will pray for the dip to continue, but people who have already accumulated a lot of bitcoin will not pray for the dip to last much longer.
Sometimes the dip is good for the longer term investor, but some might run out of money and others might get scared by the dip, which as you suggest is not necessarily the better approach to accumulating bitcoin.
Anyhow, we cannot necessarily judge what another person should do, especially if they have already been accumulating for a while.. They might be in a different stage of their investment as compared with the stage that you perceive yourself to be in right now.
Youre absolutely right from what you have said, I believe there are situations where some investors wouldnt want to see a dip, considering the fact that they have been accumulating bitcoin for a very long term and they dont want to have a scenario where there investment seems to be in a downturn because most holders will likely want to see Bitcoin keep growing so they can continue to have more profit in their bitcoin portfolio, and I dont see a chance where they will want a dip to last longer instead they will be more interested in bitcoin growing more and more for there own benefit.
There are new investors as well, who might not have that so grate financial enablement more likely having more discretionary income in their own disposal to buy bitcoin, and people who are just getting started, some of them might have different perspectives about the dip, while some might also have different opinions, because some might feel that when there is a dip it gives them more leverage to buy more at a cheaper price, while some might also feel they have been lackadaisical because they have already bought bitcoin and they dont have money to keep buying when there is a dip to stay on track, and some might as well panic because they are new.
I think everyone is entitled to what they feel makes sense to them, and they can buy bitcoin more no matter what the price of bitcoin would be.
But personally I would rather want to see Bitcoin grow more, instead of anticipating for an unprecedented dip while there are other techniques to keep buying and accumulating bitcoin like buying through DCA and lump sum, and when the price grows high I have more tendency of having more profit than thinking about a dip.
