Agree with your opinion, we cannot determine the accuracy of purchasing bitcoins, because it is very difficult. DCA only tries to buy bitcoin with a method that is consistent with the amount of money we can determine. As you said, we can set the time to shop, and of course for small investors like me we can buy a little but consistently.
DCA is more about spending money on accumulation of bitcoin for your portfolio. You don't have to spend a fixed amount of money like $100 or $1,000 for each of your DCA entry. The point is you can assign a minimum fixed capital for each entry but if you have more, you can increase the DCA capital for any DCA round.
You can DCA like a clock, with fixed time, fixed capital but you can be flexible with it too because life is not like a clock and your financial status can change too.
DCA method is definitely a good way for small investors to invest their small funds.
It is one of biggest wrong thinking about DCA. DCA is for everyone, from small to big investors.
MicroStrategy is DCA and they are not a small investor. Whales apply DCA too and surely we can not say whales are small investors.

It is your speculation and price can fluctuate with not big up or down changes around halving or it will have a surge or a massive weak down. We all can not know what will happen in future but if you have bitcoin, hold it tightly as months after a halving, we will have a massive bull market.
If you have spare money, let's be ready for accumulate more bitcoins. Don't miss the party!
