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.
Of course, you can do both.
Yet, the mere fact that you can do both does not mean that you need to do both or that it would be preferable to do both.
Each person has to decide regarding the extent to which one approach might be better than another in the context of his own circumstances.
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.
There is nothing wrong with thinking about a formula for yourself, even though some newbies may end up better reversing those numbers or to have all or almost all dedicated to DCA buying and little to none dedicated to buying dips, especially as some members already mentioned that they are going to be buying dips and non-dips through DCA,and also that there is no real way to know whether more dip is coming or not, yet surely any person could have some kind of a regular buying of $100 per week and then after becoming concerned that there might be more dip, convert over to buying $70 each week and holding the remaining $30 to buy on dips and perhaps set some kind of dip parameters, and if the dip parameters are somewhat restrictive (or at least not getting triggered), then perhaps after 10 weeks, $300 might end up building up, so even the amount of money building up (for the purpose of buying the dip), could end up contributing to some needs to reconsider how to allocate the money... and yes, individual choices.. including that the person might also receive some kind of an unexpected bonus (let's say $1,000), so then might need to consider how to allocate that money in terms of buying the dip money, DCA allocating or perhaps buying right away with some or all of it, and so sometimes receiving some kind of unexpected amount of extra cash (or discretionary income) can provide a lot of relief due to providing additional options regarding how to treat such extra cash that came into the picture.
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.
If you have money available to buy at that price, sure.. no problem, yet it can be problematic to hold very much value out of anticipation of such potential dip prices that might not end up playing out.
By the way, I surely don't know if I am very likely to be correct or not, yet for several months, maybe half a year or more, I have been suggesting that I would be willing to bet that the BTC spot price does not go any lower than 20% above the 200-WMA until the end of 2025, so that means that I have been anticipating that the odds are less than 50/50, and that is why I am willing to make such bet - yet at the same time, having bets with something in the ballpark of 50/50 odds is not really expressing a whole hell of a lot of confidence, yet maybe at least enough confidence to enter in the bet with an expectation that the odds of winning are greater than the odds of losing... so yeah, in recent times, the 200-WMA has been moving up between around $30 to $45 per day, and currently in the lower end of that range, yet surely as the BTC price goes up then the amount that the 200-WMA moves up per day will likely also move up.. and right now, BTC spot price is right around 52% higher than the 200-WMA.

Using 10% of monthly salary by salary earners is not a bad idea, I consider this one of the best approach when it comes to DCA, cause one would still have reserve funds as a leverage to take advantage of the market when their's a massive dip for instance about weeks ago when Bitcoin fell below $50k. This is the more reason why it's advised that people shouldn't loan money to go into Cryptocurrency, imagine if someone made entry with a loaned money at $60k plus and the market declined below $50k they'll end up being in a big mess cause I wonder how they'll pay off the debt, investing on Bitcoin especially when someone is using the DCA method is meant for those who got a stable income and not some jobless person trying to alleviate themselves with the little funds they got through Bitcoin.
I don't think there is any point deciding what percentage of salary others should invest in Bitcoin because that depends on a lot of factors which varies from individual to individuals. In other words, the percentage an individual should invest in Bitcoin is something the individual should work out by himself to know what will be suitable base on his level income and responsibility because the bigger picture is to invest in Bitcoin and be able to manage the investment properly so they are not sold off when there are challenges. Therefore, one of the key role of the investor is to ensure plans and provisions are made to take care of anything that might make the investment to be sold off.
I don't have any problem with folks trying to figure out some kind of a target amount that they are going to invest and/or save, and I recall that even when I was young, I would try to target something like 10% or more of my gross income to invest and/or save.
Of course, as you mentioned, there is a bit of devil in the details, and we should attempt to use the correct language, which is that no one should be investing more than their discretionary income, which truly some people have higher levels of discretionary income than others, yet sometimes we can also increase our discretionary income by increasing our income and/or cutting our expenses. So we an assess how much of our discretionary income is part of our gross income, yet we can also assess how aggressive we are going to be in terms of our use of our discretionary income for investing/savings rather than for consumption. There is no one correct formula, yet those who are more aggressive in regards to the amount of their discretionary income they invest into bitcoin are likely going to progress more greatly in their bitcoin investment, yet they might end up sacrificing other areas of their personal life, so they likely need to find some kind of a reasonable balance... that also allows them to feel that they are making reasonable progress in their bitcoin accumulation journey.
