they can also decide depending on the cash they have or an extra money which comes in to use it to lump sum. More so, if an investor accumulates a reasonable large portion of bitcoin and hold over time then there’s nothing wrong if he chooses to buy the dip, and that’s why dip buying is not for newbie investors because there’s every tendency that they will wait until its dip before they can accumulate bitcoin, which of course is a very wrong investment approach for them.
You're just mixing everything up, the fact is a low coiner or a no coiner is not supposed to wait for dip to occur before attempting to buy, as a newbie is advised to stick to the DCA. while going with this method there's every tendency that you will meet a good buying opportunity then you can use that opportunity to front load your investment instead of wasting the whole time, i agree with you when you said that there's nothing wrong if a guy chooses to buy the dip, but this approach is supposed to be applied when they must have reach the status of overaccumulation and not when they're still struggling to reach thier investment goal because going with this approach when you have not stack enough bitcoin in your portfolio is like a waste of time.
