For people think about short term its so risky for them to buy at current situation since provably the current movement of the market might confuse them and any possible correction might destroy their plan which could lead to lose their money. Waiting for dip maybe their option and this will be a long waiting time for them.
Buying dips is always great because it increases satoshis you can accumulate with same capital value, but waiting for dips requires a lot of patience and strong mentality to actually buy when market is in red and maybe under massive fud attacks.
Dips are great buying opportunities for intelligent investors, who are experienced in this market and they have strong mentality and diamond hands as they know that after dips, Bitcoin will rally, and after a bear market, Bitcoin will have a bull run with a parabolic curve.
But if they are for long term and want to do DCA I guess price is not a big issue here. They can actually buy now and start to increase their portfolio. Any unnecessary things happen in the market is provably not their main concern, since usually the target years for people who's into this kind of investment usually choose to hold for 4 - 10 years timeline. I prefer to choose this kind of set up since it gives people low risk and there's huge chance for them to get away on huge stress brought by market fuds also volatility.
Chasing for dips is not too helpfulf for newbies, with some reasons discussed above. Newbies can hope that they will have dips for purchases, but when dips come they will turn to be fearful and panic. Newbies need more time in this market, expereince more dips and rallies after that, to realize that dips are great for accumulation of bitcoin.
DCA is a strategy to avoid finding market bottoms, wait for dips, and it's a very efficient investment strategy for newbies.
