We can't tell the future outcome because we can't see the future but we can only hope for the best that's all , back to your topic I usually speak base on experiences, so when I started my bitcoin accumulation, knowing about the DCAing strategy also contributed to it (me taken my Bitcoin accumulation more serious and making it more effective).

Because I noticed that DCAing don't just help me to purchase bitcoin at lower quantities but also help me to purchase bitcoin at different price interval, whether when the price was or low , and as time goes I can easily see it's effect In my Bitcoin accumulation, which have put me in a position of been in good profits because I kept buying the dip whenever there's one using DCA strategy or method.
