You wouldn't be interested in an answer from an internet stranger. But please tell me how "dollar cost averaging" would help any investor in a real world scenario?

It actually grieves me that your average person is completely unwilling to just take a few days of their life to understand investing and what it is and how they can sensibly do it. Instead they decide to treat it like a casino and chase hocus-pocus like "dollar cost averaging" or "technical analysis" or "day trading".

Every person usually has some area of expertise or interest, or even a hunch. Take that and invest accordingly, long term. There are tools available to make any investment very conservative or very risky, according to taste.
