First, stable and normal cash flow or in accurate calculation as realistic capital to be used in making aggressive purchases, but it should also be remembered that mental health must be considered after making a purchase, it can indeed affect the buyer.
And I believe more in consistency than aggressiveness which actually makes us feel like we are losing if the bitcoin market goes down and instead becomes a fear of entering more and what is worse is taking a cut loss when the market crashes, consistently buy the dip or buy every crash is the key to investing in the safest and most profitable bitcoin of all time.
I am not really against the idea of buying dips so long as we recognize that there are trade-offs in regards to holding back value for dips that may or may not end up playing out.
So if someone is a beginner to bitcoin and they have a budget of $100 per week to buy bitcoin, they probably should be using most of that to buy bitcoin right away, and sure, if they want to hold back $25 for buying the dip, then maybe that is reasonable, since they would still dedicating the majority of their weekly allowance to buying right away.
Think of your own forum registration date of
January 2015, if you had been buying $100 every week from then until now, you would invested $53.4k and accumulated close to 34 BTC. Based on those kinds of results, I am not sure if there would have had been any need for any other strategy... in other words it is difficult to say that there is a need for some other strategy, even though surely past performance does not equal future results, even though I think anyone getting started today likely would be advantaged on starting out to stay focused on regular accumulation rather than trying to figure out if there is a dip or not and potentially changing strategies based on perceptions of dip or no dip.
