Who it is.Bitcoin isn't a company. There's no CEO, no earnings report, and no one who can issue more of it. It's a ledger running on tens of thousands of machines worldwide, with the rules written into the code: the supply stops at 21 million coins, permanently. Because it's scarce and controlled by no single institution, BTC gets compared to gold and treated as a digital store of value. What you hold isn't equity in anyone; it's a small share of the rules themselves.
Its temper.BTC has one of the wildest tempers among mainstream assets. It trades around the clock with no daily limits, and it can swing hard through a weekend. What moves the price is rarely operating numbers; it's capital flows, regulatory news and raw sentiment. It has fallen more than seventy percent several times in its history, and set new records within those same cycles. The violence isn't an accident, it's the norm, and any way of looking at BTC has to start by accepting that.
So let the tool decide.Rather than guess which day is the bottom, hand the sizing to DCA Score. BTC swings wide and falls deep, so the further price runs below its long-term average and the colder the market gets, the more its DCA Score climbs; once sentiment warms and price presses back toward its highs, the score settles down again. Low score, keep to your usual pace; a higher one means the market is handing you more room than usual.
One thing to know.The biggest difference from a stock is that BTC has no P/E and no free cash flow, so valuation simply can't be computed here, which is why the P\u00b7FCF factor never appears in its DCA Score. What matters instead comes down to four things: how deep the current drawdown runs, where price sits against its 200-week average, how large the annualized volatility is, and whether sentiment leans fearful or greedy.
Five key signals drive one unique DCA Score.
Ten years of BTC price with the DCA Score line on top — at a glance you can see how far it has run, and how many times the market has knocked it down along the way. Both lines are already stacked for you.
For a closer look, tap “hot zones” to bring up the add-on bands. Every lit band is a moment the score said “you could buy a little more” — the darker the colour, the rarer that spot.
Then use 10 / 5 / 3 / 1 year above to pull back across the whole cycle or zoom into the recent stretch. Price shows you the moves; the score shows you the timing.
The real numbers, laid out for you to use.
No. DCAcafé is a data tool that helps you think through the timing and sizing of investing in BTC; every decision is your own. Past performance doesn’t indicate future results.
BTC’s price and RSI come from Yahoo Finance’s public API, VIX from CBOE, and valuation from public financial filings. Data is refreshed once daily.
When BTC’s DCA Score reaches 60 or above, the system computes an amount beyond your base budget. The higher the score, the higher the matching cap — up to 1.8× the base. It’s the system’s cap for the period, not a rule; you can adjust it yourself.
Because market conditions change. Each time, the system re-reads BTC’s RSI, drawdown and VIX to compute it. That’s the whole point: let the amount follow the market, not the other way around.
