This strategy would have been good if bitcoin was quick to get rich soon, but since it is not, this strategy is not a good one. This strategy can make someone miss out on accumulating bitcoin because if you buy bitcoin at a low price and sell it at a high price, you will make a little profit, and if you want to buy bitcoin again, you will have to wait for the bitcoin to reduce to the price you want to buy it, and if it doesn't reduce, you will not buy it. It is good to buy and hold bitcoin for the long term using the DCA strategy so that you will be able to control your emotions and not worry about selling your bitcoin for short-term profit.
I think people who already understand Bitcoin and also understand how the crypto market can experience unusual fluctuations through several things, they will definitely not sell the Bitcoin they have bought just for short-term profits. Moreover, the profits can be very small and insignificant so taking one of the appropriate strategies such as DCA is a quite reasonable option because Bitcoin is very different from other cryptocurrencies. So it needs to be held and treated differently if everyone wants more profits by betting for a long time.
So if everyone wants more profits through Bitcoin, of course their own strategy must also be adjusted because Bitcoin, which has so far gained more interest, definitely still has good potential and can also be quite suitable for anyone to hold it in the long term. I also prefer the strategy you said because if you just buy at a low price and sell it again in the short term just because you see a small profit, I think that's not much different from trading and for some investors they certainly won't want to implement something like that.
