I'm not sure I understand your question. To reiterate, I do run experiments but I'm unable to beat DCAing into obvious winners. In fact, in retrospect my biggest losses have been around opportunity cost of not DCAing into assets that I knew would do well. 

Eg: DCAing a small amount of $ every month into Bitcoin for over a decade was the obvious, boring thing to do. Alas, it's not something I did. 

 I missed your point. I thought you were being too hard on yourself for ONLY DCA-ing instead of going for some other bet. :)
