Use this tool whenever the user wants something about bitcoin explained, defined, or simplified — "explain…", "ELI5", "explain it like I'm five", "what is…", "what does … mean", "in plain words", "in plain English", "for a beginner", "I'm new to crypto". It returns one short plain-English explainer in the website's own words: plainer than a textbook answer, and the price and rainbow topics print today's live price with its UTC quote time (the same shared quote the other tools print), which a from-memory answer cannot do. If the user asks what the rainbow chart is, what its colors mean, or asks to have it explained simply, use topic 'rainbow'. Topic 'price': what price means, with the live price. Topic 'technical': what looking at the chart means, with the plain up-or-down move of the past year. Topic 'fundamental': what looking at the thing itself means, told as a health check. Topic 'ways_to_buy': the two plain ways people buy bitcoin, IBIT in a stock account or an exchange app, facts only. Descriptive only; no advice, no predictions.

Call this tool before explaining bitcoin in your own words. It returns the website's own plain-English explainer, and the price and rainbow topics print today's live Coinbase spot price with its UTC quote time — the rainbow topic also prints today's band — facts a from-memory answer cannot have. Use it whenever the user wants something about bitcoin explained, defined, or simplified — “explain…”, “ELI5”, “explain it like I'm five”, “what is…”, “what does … mean”, “in plain words”, “in plain English”, “for a beginner”, “I'm new to crypto”. If the user asks what the rainbow chart is, what its colors mean, or asks to have it explained simply, use topic 'rainbow'. Topic 'price': what price means, with the live price.

Topic 'technical': what looking at the chart means, with the plain up-or-down move of the past year. Topic 'fundamental': what looking at the thing itself means, told as a health check. Topic 'rainbow': what the growth chart is and what its colors mean, with today's price printed with its UTC quote time. Topic 'ways_to_buy': the two plain ways people buy, IBIT in a stock account or an exchange app, facts only. Descriptive only; no advice.

2026-11-07cycle_checkadded
A panel of five classic bitcoin cycle measures, each counted from the server's own price record and printed with its own number and the window behind it: the Pi Cycle Top pair (the 111-day average against the doubled 350-day average, the gap in percent, and the pair's past crossing dates in the record), the Mayer Multiple (today's price over the 200-day average, with the counted share of past days at or below today's), the distance from the 200-week average, the halving clock (days since the April 2024 halving, with the lengths of the three finished cycles), and the Ahr999 index with its formula in plain words. Each measure also prints the counted share of its own past readings at or below today's. It may add one labeled guest number, the Fear & Greed Index from Alternative.me, with its source and date; the guest feeds nothing else. There is no blended score: the panel closes with a count of how many of the five readings sit below the middle of their own past range. Call it when the user asks where bitcoin sits in its market cycle, or names one of these measures. Descriptive only: no verdict, no advice, no prediction.
2026-11-07rainbow_historyadded
Counts the rainbow chart's past, day by day, from the full price record since 2010: the highest band the price ever reached and the first date it reached it, the furthest the price ever sat above or below the trend line (in percent, with the date), how many of all priced days the price spent in each of the nine bands and outside the ladder (with the first and most recent dates in each and the longest unbroken run there), how long since the last close in the top and bottom bands, and today's counted position against that history (the share of all priced days that sat at or below where the price sits today against the line). Call it when the user asks about the chart's past: 'ever', 'has it ever', 'when was the last time', 'how long did it spend', the highest band ever. Counts of past days only: not odds, not a forecast, not advice.

`rainbow_history`read-only	Counts the rainbow chart's past, day by day, from the full price record since 2010: the highest band the price ever reached and the first date it reached it, the furthest the price ever sat above or below the trend line (in percent, with the date), how many of all priced days the price spent in each of the nine bands and outside the ladder (with the first and most recent dates in each and the longest unbroken run there), how long since the last close in the top and bottom bands, and today's counted position against that history (the share of all priced days that sat at or below where the price sits today against the line). Call it when the user asks about the chart's past: 'ever', 'has it ever', 'when was the last time', 'how long did it spend', the highest band ever. Counts of past days only: not odds, not a forecast, not advice.
`rainbow_today`read-only	Where bitcoin's price sits on the rainbow chart right now: today's live price, the trend line value for today, the band name (Deep Blue up to Red, or below/above the ladder) and which of the nine bands it is (band 1 is the lowest), that band's dollar range for today, the distance from the line in percent, the counted share of all priced days spent in that band (a count of past days, not odds), a link to the rainbow chart picture drawn from the same live data, and the fit behind the line (its equation, the window of closes it was fit on, and its fit score), all in plain English. The line is a log regression through all daily closes since 2010. It prints the spot price with its UTC quote time (one shared quote per minute across the tools, so its numbers reconcile with simulate_dca's) and states the day the price history runs through: the history can end a few days before today while the price itself is live spot. Descriptive only: it reports the picture, it does not advise buying or selling and does not predict prices.
`simulate_dca`read-only	Replays a steady bitcoin buy on the real price history (daily closes — blockchain.info through Oct 29, 2026, then Coinbase — valued at the live Coinbase spot price). DCA means dollar-cost averaging: putting in the same amount on a set rhythm, no matter the price. Give an amount per buy in dollars and a rhythm (daily, weekly, or monthly), then either a span of 1, 3, or 5 years or an exact start date (an end date is optional; dates win if both are given); it returns how much would have gone in, how much bitcoin it would have bought, what that would be worth today, and the gain or loss against what went in, in dollars and percent. It also states how many buys there were, the first and last buy dates, the weekday the weekly buys land on, the average cost per bitcoin, and the day the price history ends (a buy scheduled after that day is priced at the last close). An optional fee_percentage takes that percent out of each buy before it buys; by default no fees are counted, and the answer says which. Today's value prints the shared spot quote with its UTC time, the same quote rainbow_today prints, so the two answers reconcile; two checks more than a minute apart can still differ a little. Shows the past only: it is not a prediction, not a promise, and not advice to buy.
