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.

Brother trust me in a bear market all of your liquidity will be drained if you do DCA. I know this because I have done it. Every month price of my project making new lower low and I can not do anything but put more money into it. Actually, I am trapped with those projects. So it will be best to wait for most of the major coins to dump over 80% from their ATH after a bull season and then start accumulating coins.

I have already mentioned in my first post how to identify one. In a bear market price of most coins will gradually create a lower low. Yes, you could see some recovery after every crash but it will crash repeatedly. This is how a bear market reacts. It is not that hard to identify a bull or bear market and in every bear market, most of the coin prices went below 80% of their ATH. You can check that by yourself.

I haven't heard of this strategy, I believe, but I fail to grasp how this is better than other things.

Why isn't it better to wait till the price is quite down (say, at least -30% from the ATH), and invest $10k then? It would mean buying more BTC than if a person buys when the price is high.

This kind of Model can only work with bitcoin, if you try to do dollar cost average with altcoins, you will bleed the hell out of your capital and you know what happens to altcoins in every bear market...

In a bull market, it is the opposite. Most of the projects made multiple X within a month. This time we saw the ROI is lower because the market becomes bigger. Do not look at the ROI instead look at the amount of volume or money inflow in this bull season compare to the previous one. You will be this number is getting higher in every bull season. I am also sure in the next bull season we will see multiple X cash inflow than this season but the ROI will be smaller than this season. This is the nature of crypto. The more mature the market will become the less volatile it would be.

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 don't think this is necessarily the case.  Most of my clients dollar cost average by default, as with retirement plans you've normally got money coming in to your plan from your work paycheck every two weeks, so by nature they are dollar cost averaging and not even knowing it.  Now if we are talking about outside of your normal retirement plan investing, then I would probably agree with you.  But I think most of those times are simply people placing trades when they have the money to do so versus trying to time things.
