There are stages in your bitcoin accumulation journey that you need to tweak from one strategy to the other and no just depending only on one strategy. For instance, investors that have accumulated a good size of bitcoin but have not reached their bitcoin target can wait for the dip to buy bitcoin at discount so that he will add a significant amount of bitcoin to his portfolio and might not DCA anymore.
The only thing that can make someone go into different strategy is when they have multiple sources of income because we cannot suggest for someone who is barely managing to sticked on there DCA accumulation to consider adding more other strategies into there investment patterns because they would be over pressed with the load of maintaining those strategies, though having or adding more strategies is not wrong if you are financially capable but for those who are less privileged should continue with DCA instead of thinking about how they can get more Bitcoin when they don't have the financial strength.
