In fact, even if, for some reason, you're a sociopath and absolutely impervious to emotion, DCA frees you up to live a regular life. This means building a career, or pursuing a hobby, or fine-tuning a talent, or growing a family... whatever it is you'd have been doing if you didn't know about Bitcoin.
I think too many people "get into Bitcoin" and it consumes their life. Good for them, good for all, but many of these guys "get in" with the wrong expectation. Thinking they can learn enough to outsmart the rest of the market.
DCA just means you make yourself useful as you otherwise would, while at the same not missing out on the biggest financial opportunity in our lifetime.
