Easier said that done, suchmoon.. especially if wanting to carry out something like that in a somewhat seemingly perpetual way.. such as all the way down to zero. (in theory). .
I recall some guys saying that they were "all in" (or they ran out of money) when we dipped below $50k... and we are way into Down price territory that even the staunchest of DOWNity preparers (who are bullish.. so also wanting to prepare for UP) have decent odds of running out of money...
What happens if we run out of money? Is that possible? then have to go into HODL status, no? Surely if you have a cashflow then largely that would be "technically" characterized as DCA at the point of running out of money and buying as the money comes in.
As long as fiat exists in some substantial form, I think I will always have some sort of fiat revenue (job/business/real estate/retirement/etc), so barring catastrophic health failure or other life-altering events - yes, I can ride it pretty much to zero. Not that I'm planning that. Right now for example I'm just setting up an order for 10% of my free cash ~10% below spot, I don't give two shits about TA or some other woodoo, when the orders hits or price moves in the other direction I redo the order, etc. So even if it drops precipitously and quickly, I won't really run out of cash albeit the buys can get smaller.
All-in, or margin, or any of that tarding nonsense - nah. I'm happy to leave that to shitcoiners, Reddit gamestoppers, and other noobs itching to get fucked by Wall Street.
