A regular DCA will cover any dramatic dips that's the whole point of it, what if it never reaches 900 again or reaches 5k before then, nobody knows so just dca on red days. No need to complicate it
You're assuming people have an endless supply of money to DCA.
There's a smart way to DCA and there's a reckless way. Be smarter so you don't waste money. More money available means you can spread your budget out to different coins or buy more of one.
I'm sure someone thought buying Matic at this level was okay and they'd just dca if it went lower:
You bought at 1.15 but now it looks like this:
You could have waited, bought at .55 and started your DCA there since .32 looks like it could possibly be the bottom. Start to DCA where there's less downside potential.
You set aside $500, DCA high, and at the end you have 800 MATIC but the person who DCA'd lower has 1200 MATIC. It's clear who's making more money.
