This is not really DCAing method works, you're a confuse.
DCA is simply utilizing a specific amount which to invest consistently either weekly, quarterly, monthly that won't exhaust you after set aside your expenses, discretionary funds and also emergency funds as you invest to avoid tappering or tempted with the invested amount.
This simply allow us continually invest in the market irrespective of the market situation at any moment. From your explanation anyone would get exhausted, which capital seriously, how about our daily expenses to be met up. It doesn't meet the criteria before indulging in it, more or less investing without plan.
That's exactly what I said but just in a different way. I know that normally when people buy a specific asset after a specific time interval regardless of its price is what is called doing DCA, but that doesn't mean that a person needs to specifically wait for that interval to make another purchase.
If you have a budget in your hands, you buy Bitcoin at $65k with 10% of that budget, and Bitcoin drops to $60k tomorrow which is always possible, you can go ahead and buy Bitcoin at $60k with 10% of your remaining funds, and continue doing that for whatever price you deem fit for your investment plan until you have invested all your money or you think that you should stop buying as the price might start going up from there.
Nice, it based on the investment plan of any individual and how far he/she want to go with a target that gears them wether to be aggressive or conservative in there accumulation journey. As you said,I don't support the idea of anyone to stop buying Bitcoin wether the price pumps or dumps, I think it should be a long run (probably lifetime), journey to keep accumulating (reinvesting), after you might have taken your profits, but you keep going since it a valuable asset and already have proven itself and we still don't know what the future holds for us, not being too optimistic though.
