Unfortunately while DCA being one of the most effective strategies for non market pros, it's probably the most boring method hence why most people don't want to do it. People get really addicted to the adrenaline rush of getting in and out of positions, not knowing that most of them are just basically gambling because they're doing things blindly.
I'm gonna go old school and just say
word up to that, buddy. I've never looked into the advantages of DCA investing, but I've done it with retirement accounts in the past where money was taken out of my paycheck every week.
For the crypto market, though? I don't think a lot of folks on this forum do it, either because they don't have the discipline or simply don't have enough money on a regular basis to plow into bitcoin or whatever altcoin they're into. I mean just take a look at all the obviously desperate bounty hunters there are, working for shitty tokens that might be worth nothing (assuming they even receive them at the end of the bounty period). I have a feeling they're trying to earn crypto to buy basic need items and probably aren't building a crypto stash.
With respect to this most recent crash, I'd point out that dollar-cost-averaging would only protect you if your average purchase price was less than $30k or so, and it won't always prevent you from "losing more". You can actually lose everything depending on what you're investing in.
