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.
Using 10% of our monthly salary is never a bad idea as long as the reserve is able to sustain you till you are able to refill it again, so actually is a note able ideology that 10% of monthly salary is a kind of fraction that shouldn't present any challenges of using it but sometimes it can be too much for most investors to use because there are people who has a very large family and there consumption is also very high so you can see that doing 10% without some consideration will certainly affect the investors, so perhaps bringing it down a little more will also be a good idea for such investors. Also concerning the place you mentioned about investing 90% of our savings don't you think is a bit too high?.
