So they invest in bitcoin by DCA, or buy dip, then lumpsum is their desire because the goal is to buy bitcoin when they think the price is suitable.
If a person is investing into bitcoin and if they have a 4-10 year or longer investment timeline, they might not be too concerned about the BTC price. I will concede that there are likely folks who get overly worked up about the BTC price, and it might work to their disadvantage to get worked up about BTC price if they are either a no coiner or they might consider themselves as not adequately prepared for UP prices. The only way to prepare for up if you are not adequately prepared is to buy, and waiting does not prepare you for up, it ONLY prepares you for down.. which seems to ONLY be a good strategy for someone who has assessed that he already has enough bitcoin and/or preparation for up.
Yes you are right when you are accumulating and holding for a very long term you won't bother yourself about Bitcoin price, I never knew today that Bitcoin had a little dip I was told by my friends who where into short term investment you can also decide to call them traders about the dip in Bitcoin some of them started to panic, however me that is accumulating and holding for long term really didn't care about the price and I was never in any panic because of my long term holding goal, the people that are mostly concern about Bitcoin price are Bitcoin traders and not long term investors.
