I think everyone who invests in Bitcoin definitely has time to organize their purchases and why DCA is so popular because they invest in the long term with hundreds of purchases throughout their investment journey. Of course DCA is the best and maybe buying at the same time is not too popular if the market situation is bullish. Apart from that, at a special level, continuing to pay attention to the charts is of course not something that everyone can do because they don't have much time due to their busy work, therefore those who focus on DCA will visit the market when their purchases are due and they do it like once every two months or once a month.
And it is true as stated by JJG because in point 8 where we can change our formation when the market situation changes suddenly, that is, we make purchases before the time comes in the composition of the list of purchases that we will make. It all depends on the situation because they can act more aggressively when the market turns red and can also accumulate more when the market falls 10%.
Techniques like technical, fundamental and sentiment analysis aid anyone who is investing but they do require time and expertise which everyone dont have. If I talk about myself I dont have expertise to in TA, FA and SA, thats why I follow DCA.
I was doing a small research that how much effective DCA will be on
https://dcabtc.com/ and comes up with following data. If you doing DCA 100 dollar per week then here are results:
DCA, 100 USD per WeekPeriod | % Change | Total Invested in USD |
Accumulate for 1 year. Starting 1 year's ago --> | 1.93 | 5300 |
Accumulate for 2 year. Starting 2 year's ago --> | -5.98 | 10,500 |
Accumulate for 3 year. Starting 3 year's ago --> | -8.98 | 15,700 |
Accumulate for 4 year. Starting 4 year's ago --> | 18 | 20,900 |
Accumulate for 5 year. Starting 5 year's ago --> | 69 | 26,100 |
Accumulate for 6 year. Starting 6 year's ago --> | 94 | 31,300 |
Accumulate for 7 year. Starting 7 year's ago --> | 238 | 36,600 |
What I conclude from above table is that even DCA may not be effective over a small period of time but over a longer duration like 4 years or more.
