If they can buy in bulk then maybe its good for them but if they do DCA maybe they should start as early as they can since this is I think more better decision to do compare of waiting for unnecessary dumps.
You could do both.
¯\_(ツ)_/¯
After all of these years talking about this buy the dip topic, you should realize and appreciate by now that there are always tradeoffs for anyone who decides to hold back value in order to wait for dips that may or may not end up coming.
I learn and continue to learn and I have accepted the fact that a person can do BOTH if he/she chooses to. Because, why not? Both have their advantages in an accumulators' strategy.
Purposefully holding off for dips seems to be way more logically justifiable after a BTC accumulator had already accumulated a decent amount of BTC, and even then, they may mis-assess how much is a decent amount of BTC, so likely it remains way better for a BTC accumulator to largely focus on regular DCA buying through a whole BTC cycle before starting to try to strategize buying dips, unless they have abilities to front load their BTC investment, which would have had put them into a different position from someone who is ONLY able to invest 10-15% or less of his disposable income into bitcoin.
If you ask me, it's more about use about 10% of monthly salary to DCA, then save the rest. Because if we are lucky, and a golden opportunity comes again - it might be a good time to be irresponsible and use up to 90% of your savings to buy the DIP.
I merely use the 200-Weekly SMA as a guide to ascertain a "Golden Opportunity DIP". It's currently $38,670, if the price crashes near that or under, that's high probability a good purchase.
