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.
I love what you said, what are we even looking at the charts for since we are strictly investors, I think that chart should be for people that has chosen to be traders no real bitcoiners, as a long-term investors, I think your major target is to keep accumulating Bitcoin as much as you can not giving in the time that you would've given to your investment to check some charts that has no value to add to your investment journey instead it can only discourage you to keep doing the needful, personally and honestly whenever I hear this chart of a thing in things relating Bitcoin, the first thing that comes to my mind is traders behavior because I know a real investor that understands how this investment works wouldn't have the time for such, fluntuation and volatility is a Bitcoin thing so anyone checking price all the time to still confirm this fact aren't doing him or herself good health wise, just as you said DCA is their what's there to check again when one can actually use this method to achieve his target in the said investment on a slow and steady mode process.
