Start buying at timed intervals, On the long run you increase your stack and got less worries about the price. It will give ease of mind to not check the charts every x minutes ; )
If we invest in Bitcoin regularly at regular intervals every week using the DC method, our risk and mental stress will be reduced. In this case, no matter what the price fluctuations, the value will remain stable. Our confidence will also increase. Also, we should stay mentally healthy without looking at the chart again and again.
Dollar Cost Averaging (DCA) is a simpler and less stress-free method of investing in Bitcoin than any other. I agree with you. The advantage of this method is that you can allocate any amount of dollars from your discretionary income during price fluctuations. You should plan to continue saving at any size you can afford. You should also have an emergency cash fund with the DCA method to keep it going for a long period of time.
