Planning is the first stage of anything that is associated with consistency. It is following the plan that is called consistency. DCA is itself a plan and following your DCA is the consistency.
I get your point, but I don't see consistency as just following your plan, as plans can be followed in different ways. Let me say, for instance, that I have a plan to accumulate 1 Bitcoin before the end of one year, and initially I strategize to buy another 0.08335 before the end of every month. In the first two to three months, I was able to achieve that, but because of some kind of personal issue, you decided to shift out the amount you want to accumulate this month, but with the belief that you will be able to gather more than you plan for the next month so that you can cover up the balance of last month.
In such a case, I don't see that as consistency, as I view consistency as the process of doing a particular thing constantly, nonstop, until the purpose of that thing is achieved without even bridging any of the set-out plans along the way.
You've raised a valid point worth considering, but I still find myself agreeing with oduhu. He mentioned that consistency lies in following the plan. For instance, if the plan is to accumulate $1000 worth of BTC by year-end, and I achieve this goal each year using the DCA strategy, then I am consistent. The specific methods I use to reach that goal within the year might vary due to trends or economic factors, but the important part is maintaining the consistency of achieving that $1000 worth of BTC annually.
