Buying the dip depends largely on individual, if you have knowledge of the market and how it operates then buying every dip would be very satisfying, but from the point of a newbie who had already bought from the top and has less or limited knowledge of the market won't even consider it, their eagerness would be to sell and leave,
I would rather buy in every major dip than in every dip, although the former comes rarely.
You seem to be projecting too much on the financial, budgeting and investing situation that others might find themselves in.
If you understand the concept of buying on the dip, it should be used to attempt to supplement a kind of dollar cost averaging approach to buying BTC rather than attempting to time BTC price dips, because it is nearly impossible to figure out with any kind of precision when dips are going to happen or how much dip is going to happen.
So, in this kind of a system, you might establish a buying budget for yourself that covers a period of time. So for example if you have a $6k budget for the next 6 months, so if you divide such budget into weekly allotments, then you would have $250 per week for your budget.
Therefore, you might used some of that allotment to buy BTC every week, maybe $125, and then the other half $125 might be used to buy on dips, and of course, you can establish how much of a dip that you need before buying and you can choose to carry over the allocated amount to subsequent weeks... there are a lot of ways that you could allocate any budget, once you have established such budget in terms of both amount and time frame.. and you can even tweak a bit here or there in your carrying out of the plan based on changes in your ideas including how you might approach buying on dip practices.
