If you have accumulated enough Bitcoin and then decides to only buy when bitcoin price is low it wouldn't be problematic because you have already accumulated to your satisfaction and decided to buy only when there is dip, but very problematic when you only buy when the price of Bitcoin is low which is always done by traders, accumulating Bitcoin using the DCA strategy is very much recommended for investors to accumulate Bitcoin with since you can be accumulating bitcoin both when the price is at highs or low without always waiting for it to get low before accumulating Bitcoin.
Those who always wait for bitcoin price to drop before accumulating Bitcoin don't value or know the value bitcoin holds they are not aware that bitcoin is a great asset that we need to accumulate enough and hodl for a long time for the sake of our future and generation to come.
In the previous cycle I did the same, when bitcoin became more expensive than 40k I stopped buying, but continued to accumulate stablecoins, there was a lot of hype then and all the headlines said that bitcoin would go to 100k, but it only reached 69k and went down, but I was in no hurry to buy, I waited for it to go below 30k, and then I started buying and bought all the time until the price reached 40k again, after that I stopped buying again, but as before I continue to accumulate stablecoins.
This time when bitcoin reaches 130k (because I believe that the bull run is still ahead) I will sell some, maybe even most of it and wait for a new bear market. Maybe this time in a bear market I will start buying earlier, around 50k, I am not ready to say for sure yet I will act according to the situation, assessing the market. I admit that Bitcoin may at some point reach a point where its volatility will decrease significantly if governments start buying it for their reserves, but until then volatility may persist.
