Because the DCA strategy reduces the price volatility to some extent.
Even if one makes use of DCA Strategy the price of Bitcoin will still keep going up and down after you buy. So I would say this-]DCA Strategy doesn't "stop" rather does it even "reduce" volatility.
What we can say that DCA Strategy does is that it helps spread your buys so you don’t risk putting all your money in at the worst timeNo, I disagree on this your highlighted statement here buddy, the very purpose of dca accumulating strategy is to make accumulation of Bitcoin very easy and affordable even for the poor, because you can be buying it bit by bit according to your financial strength, and point of correction, their is no worst time to buy Bitcoin, because it's still very cheap when compared to how much the value can rise up to in the future, so what you said in the highlighted words are false.
Additionally, volatility is part of the nature of Bitcoin, so it wouldn't go away all of a sudden because you are accumulating through the dca strategy.
I agree with you Mr finebone because many folks failed to understand that DCA is the easiest method in accumulating Bitcoin regardless of your financial capability, and it also gives everyone including the poor an opportunity to be a partakers in bitcoin investment and its potential, however the future potentials of bitcoin is way beyond human imagination so it will be too bad not to invest now that bitcoin is still affordable and accessible through dca strategy because their will be a time when bitcoin price will hit it's peak and I believe it could be too late by then.
