You make a great point. An investor should probably know how to retain and increase purchasing power if not volatility will be a thing that they know of but will be scared of. And even in DCA investors might get low on funds in purchasing Bitcoin with the actual amount they've been using. Most times it is a result of lacking a steady stream of income which may be that they lost their job without having a business or any other investment to tap from. To be more realistic, investors and aspiring investors should have a decent approach while investing. They need to be smart and watch the source they get the money they use for their investment. Whenever we feel uncomfortable with our investment, we can have a shift in the amount we use in investing so we don't crumble our business or do anything that will affect the source of our income. While accumulation is important if we see a means to make more money than we can venture into it after making observations and having our conclusion on it. This doesn't mean we get to stop our accumulation entirely. Rather we can reduce the percentage we use in investing so we can get things right and working smoothly for us. Although it might take some period for the business or investment to start yielding something for us. In the end it's still a better approach.
