Why DCA works better in volatile markets
DCA works because it turns timing risk into process risk. Instead of putting all your capital to work at once, you divide it into repeated contributions over time. That reduces the impact of any single entry point, which matters in crypto because large daily swings are normal rather than exceptional. A disciplined schedule can also improve behavior: you stop refreshing charts in search of certainty and start following a rule you already chose when you were calm.
That said, DCA is not a magic shield. If you buy poor-quality assets again and again, the schedule does not fix the thesis. If your allocations are too aggressive for your actual risk tolerance, the strategy may still fail behaviorally because you stop contributing during stress. DCA is strongest when it is paired with a credible portfolio design, a realistic time horizon, and enough cash management to keep the plan alive through corrections.
