I spent seven years as a traditional financial advisor, and I watched far too many people pile in at the most expensive moment and bail out at the cheapest. In 2020 I started dollar-cost averaging into bitcoin myself — not because I can predict prices, but for the opposite reason: because I admit I can't.
DCA is built for ordinary people who are honest enough to say they aren't geniuses. It gives up the fantasy of buying the bottom and selling the top, and in exchange you get the calm of not watching charts all day, and a decision handed to discipline instead of emotion. This site is a record of that method itself — and of every pothole I've stepped in along the way.
— Go slow, and you'll often get there faster.
If you had put $200 a month into bitcoin from the start of 2021 — no timing, no skipping…
Figures are approximated from bitcoin's public monthly closing prices. This stretch also included the 2022 crash in price — the account was underwater for a while, and that's exactly what DCA asks you to sit through. Past performance does not indicate future results. Plug in your own amount and start date and run it yourself →
Buying bottoms and selling tops is a delusion only a few ever live. DCA drops the prediction game and hands your buying over to a fixed rule — you don't need to be right about the market, you only need to not get off the train.
What usually decides the outcome isn't how low you bought, but how long you stayed in. Compounding is a quiet machine — as long as you keep it running.
Set up automatic buys, then go live your life. No daily chart-watching, no anxiety over every move — this is the most underrated benefit of DCA.
What DCA is, why it works, how to set up automatic buys, how much to invest and for how long — the whole method in one piece, ready to act on by the time you finish.
Using real historical data to show why "staying invested" decides the outcome more than "buying the dip."
Which slice of your spare money should this be? Should you take profit? How do you stay calm in a crash? This covers the genuinely hard part of DCA.
No mysticism, just the practical steps: choosing a platform, what to watch when you sign up, how to set up a weekly auto-buy, and how small your first buy should be so it doesn't sting.
Don't size it down from "how much I want to make" — size it up from your cash flow. A formula that won't force you to quit.
An unrealised loss is built into DCA, not a failure. How to tell "the account is red" apart from "the method is wrong."
DCA is the accumulation phase, but the money is meant to be spent. Three sound ways to take profit, and why you shouldn't sell on a gut feeling.
Afraid of chasing highs, afraid of missing out. DCA already gives up timing, so a bull market just means you buy less per dollar — but there's one thing you must never do.
Value averaging sounds cleverer — but is it really right for ordinary people? The honest cost, and an honest conclusion.
Same method — so where does crypto differ from traditional assets? Volatility, correlation, regulation and custody, across four dimensions.
Does frequency actually change the outcome? The data answers, and why "what you can stick to" matters more than "what's optimal."
Academic research says lump sum has the higher expected return, so why do I still recommend DCA for most people?
When the account is a sea of red, the hardest part of DCA isn't technical — it's psychological. How to coexist with fear.
Pausing the plan, chasing rallies, checking constantly, using leverage, investing money you can't afford to lose — I've fallen into most of these myself.
Bitcoin, Ethereum, or a basket? The logic behind choosing what to buy, and why "less is more."
An invite code is entered once at sign-up and can't be changed afterwards. What it actually saves a long-term DCA investor.
Roughly where the feature lives, which choices you'll make, and what happens once it's set. Hand the discipline over to the system.
No comparing on dimensions that don't concern you — just a framework you can apply yourself.
Cost is one of the few variables a DCA investor can control. The mechanics, plus a method for keeping it down.
Enter an amount and a start date, and see what DCA would have done using real historical prices. More vivid than ten articles.
