i feel it is the other way around with dca strategy on the basis of the fact that you buy at certain key price levels with the sole aim of getting a much better value as an entry point which will put you in a better position to make more profits. Microstrategy uses this strategy to accumulate more bitcoin and they would be in big profits in bitcoin turns bullish again. Right now, their average buy is around $24000 to $28000 even though they bought bitcoin from the highs of $40000
The big assumption behind investing in BTC is that it performs greatly on a scale of years, so there's only one good entry point - buy as early as possible. The exception to this rule is if we're in the middle of bull run or just entered a bear market, because the price could go lower in short term. But this just means that you should wait for the bottom.
Microstrategy is doing okay, but if they went all-in at $10k. they would have been better now. Why buy the dip at $50k and $40k if you could have bought at $10k?
