Auto-Invest vs Manual DCA: 12 Months of Letting Data Roast My Ego

For years I was that person:

“I don’t need Auto-Invest, I am the strategy.”

So I did the boring thing devs hate: I tracked both for 12 months — Auto-Invest vs my perfectly “rational” manual DCA.

Spoiler: the spreadsheet was not kind to me.

The Experiment 🧪

I ran two parallel approaches:

  • Manual DCA – same coins, same target amounts, but buys done “when it feels right” (aka after 3 hours of chart staring).
  • Auto-Invest – fixed rules:
  1. buy every week
  2. same amounts
  3. no feelings, no Twitter, no “this time is different”.

Same assets, same horizon. The only variable: me.

Where Manual DCA Failed (Aka: My Brain) 🧠💥

Patterns from the data:

  • I delayed buys after dumps: “it might go lower”. Often it didn’t.
  • I FOMO’d into green candles: “momentum is strong”. Momentum then died.
  • I skipped entries during bad news, then bought higher once “it felt safer”.

On paper, I “timed the market”.
In reality, I paid a premium for emotion.

Where Auto-Invest Quietly Won 🤖✅

Auto-Invest didn’t care:

  • red? buy
  • green? buy
  • boring crab? buy

It averaged into better prices than my manual genius most of the time — simply because it never skipped the ugly days (which, surprise, are often the best entries).

And here’s the important part:

For larger capital, Auto-Invest scales even better:

  • big tickets get split across time automatically
  • less slippage from one huge “YOLO buy”
  • fewer catastrophic “I aped $50K at local top” moments

If you’re moving serious size, automation isn’t a luxury — it’s risk management.

What I Learned 🚦

  • Manual DCA is great… until emotions show up.
  • Auto-Invest is boring… and boring compounded over 12 months usually wins.
  • The more capital you deploy, the more you want systems, not “good days”.
