It's probably the least risky strategy for a newbie; it enables you to lower your average purchase price by acquiring coins on a steady basis. Personally, I'm not buying Bitcoin myself, but I'm receiving it on a weekly basis from my signature campaign, which can also be considered a form of DCA. I'm not too bothered by market fluctuations because my average purchase price is quite low, judging how high Bitcoin has gone in the past. Even now that the market isn't performing too well, my bitcoin's value hasn't lowered too much, and every bear market is an earning opportunity, as it's more affordable to purchase larger amounts of bitcoin.
