People that are DCAing regularly weekly or monthly are still buying at the dip because they are just buying and buying and buying all the time without stopping. This is why DCA method is the best method for new investors to use because it gives you the opportunity to buy both at the dip, the bottom line of the dip and when bitcoin price is high since he is investing in a long term. It is not good for beginners to think of buying bitcoin only at the dip and that is where some of them get it wrong because what if the dip did not come, they will still be sitting on the fence waiting for the dip and watch others building and growing their bitcoin investment.
Doing DCA does not need to be when prices are down, just do it all the time while they are still able to do it because DCA is a weekly/monthly routine purchase so don't look at the price being up/down continue the task because DCA as I understand it is like that.
While buying when down is called Dips with the funds they have prepared to take care where bitcoin goes down then he is ready to buy dips.
Buying at the dip is for old investors who have accumulated a good size of bitcoin and don't see any reason to DCA anymore because it will not add much increase to their bitcoin stash, such investors can wait for the dip in other to buy at once with the money that they have kept for that. DCA is good for a no coiner and low coiner.
All can do it including beginners not also in the designation of old investors and even if a beginner wants to start by buying when dips he can do it as long as finances are ready when prices are down.
So for beginners there is no word for old investors or whales, they can do it as long as which investment strategy they think is good and comfortable, then most people have DCA because it is done every month when they receive a salary.
