Why would lump sum become "the best?" Surely if someone has a lump sum in front of them, they can still choose within the three categories of DCA, lump sum and buying on dips in order to figure out how to treat that lump sum amount that they have in front of them... and if someone might have $100 per week that they are usually investing based on their discretionary income, but then all of a sudden they get a $1k bonus, so then they can completely treat that $1k as part of their DCA.. they just buy right away, and maybe that is considered lump sum or it is considered to be just extra money that automatically goes into BTC, whether it is part of the regular income or it happens to be some extra income that happens to come in... ON the other hand, the extra amount could trigger some consideration regarding whether to invest all of it right away, to hold some for buying on dips and or to spread it out in order to include it within the upcoming DCA amounts, perhaps doubling the DCA amounts for the next 10 weeks or maybe even adding 20% to the DCA amounts for the next 50 weeks, and maybe how to treat the extra amount might have to do with how much BTC the person already has, but they might want to try to predict the direction of the BTC price, and so if they are thinking that the price might be coming down or staying flat, they might feel some advantage in spreading out their DCA or strategizing to buy on dips, however, if they are feeling particularly bullish, they might error on the side of buying most if not all of it right away... . And, the guy might end up being correct or not in terms of whatever strategy or strategies he chose to employ for the extra amount of dollars that he had ended up receiving.
I totally agree with you here. Lump sum cannot be the best in terms of investing in Bitcoin. I see it as a secondary approach to become investment because at any time there are some money that seems to be extra on top of what we expect to be our weekly income. Such money and bonuses should be used to lump sum, unless one could possibly choose to save for a long time and then lump sum which sounds so stupid to me. I don't see any good saving in fiat and then waiting for the right time when the money is enough to lump sum and buy huge while all those period Bitcoin has been doing some great movement which if they had bought by then they would have a good portfolio and be on profit. I can't imagine saving 60k for decades just to buy Bitcoin when i would have bought since.
Levels of aggressiveness should not be measured in absolute terms, but instead within the amount of discretionary income that you have, and so yeah a person with higher income could buy more BTC but that does not necessarily make him more aggressive than someone with lower income and who might be using all of his discretionary income to buy BTC. Maybe we can take some extreme examples.
One guy has $100 per month of discretionary income and he uses all of it to buy BTC.. This guy is quite aggressive and maybe even bordering on over aggressiveness (especially if he miscalculates his expenses or if he does not have reserves in place).
Another guy has $2k per month of discretionary income and he invests around $100 per week into bitcoin, which might be considered moderate and maybe even whimpy.
Of course it is true that someone can increase purchases aggressively when their finances increase from the income they earn. I think everyone has an uncertain income in their job like a monthly bonus from where they work. so their routine of executing $10 per week can certainly change to be more aggressive such as increasing it to $50.
I even often do this where when my finances improve from average or get a bonus, of course I can increase to be more aggressive in the next purchase. So, if income is relatively stable, of course we will return to the initial planning by executing at the usual level that we have done.
Without realizing it, over a long period of time, our BTC holdings increased faster than the initial plan because at each stage we could act aggressively or continue to try to increase the amount of purchases to become larger.
This comprises the investment journey of an average investor. I feel that only the rich are comfortably being aggressive in their investment and not everyone has an uncertain income in their job. There are investors that has a fixed income for a long time and by so doing they only stick to buying through DCA.
