We need to consider that we will not always have a large amount of funds ready at once, so in this case DCA is possible. Although not all of them are like that, most people, including me, are always constrained by financial conditions and it will be very difficult if they buy btc in large quantities at once so by thinking about things like this, I prefer to make gradual purchases with the time and amount I want beforehand.
This is in order to maintain our consistency in making purchases and in order to maintain the financial condition that we have from income to remain stable and the purchase of bitcoin does not affect the expenses we make every month.
Got the point here, As JJG also tried to emphasize the same thing before, and I got this point from there already but thanks to you too as conditions are not same for everyone as I do not know what the conditions of your country are but the conditions here in mine are too bad. Political leader are next lever corrupt people and those who raise voice are put in jail even our Ex-Prime Minister is put in jail and those who went against that case also put in the jail. TBH things in my country got out of hand. But still, the party which put all of them in jail are now enjoying in UK.
Enjoying their time with girls, point is they could do whatever they want but at least they should provide a voice of freedom. Not to mention media is their pet. Well, I think things are going off topic here as I do not know if I should discuss that much about my country. But my main point was to say things are not easy here and as JJG was saying he has done aggressive accumulation back in 2014 and 2015 and If I was aware of the BTC at that time then it would be easy to accumulate them in compared to this time.
Overall, I did get the point that Lump Sum need big money while DCA could be done using small amounts too, but DCA took long time to book profit while in Lump Sum we could also make instant or quick profit in shorter time.
