Czym jest Bitcoin Rainbow Chart Calculator?
▾
The Bitcoin Rainbow Chart Price Band Calculator maps the current Bitcoin price onto logarithmic regression bands that color-code market sentiment from deep blue (fire sale, maximum undervalue) through green (accumulate), yellow (fair value), orange (FOMO intensifying), to dark red (maximum bubble territory). The chart is based on the observation that Bitcoin price follows a long-term logarithmic growth curve, with cyclical deviations above and below the trend line that correspond to market euphoria and despair. The mathematical foundation is a logarithmic regression fitted to Bitcoin historical price data since its genesis in January 2009. The regression takes the form log10(Price) = a x ln(Days Since Genesis) + b, producing a curve that increases over time but at a decreasing rate. The rainbow bands are evenly spaced multiples above and below this regression line, creating 8 to 10 colored zones that have historically corresponded to optimal buying and selling opportunities. The Rainbow Chart gained popularity because of its remarkable historical accuracy through multiple Bitcoin cycles. Prices in the blue and green zones (2011, 2015, 2018-2019, 2022) consistently preceded major bull runs, while prices in the red zones (late 2013, December 2017, November 2021) marked cycle tops. However, the chart creator explicitly states it is not investment advice and that the model could break if Bitcoin adoption curve deviates from historical patterns. This calculator allows you to input the current date and Bitcoin price to see which rainbow band the price falls in, compute the logarithmic regression value for today, show the price boundaries of each band, project future band values (what price levels correspond to each band 6, 12, and 24 months from now), and overlay the current position against historical cycle positions at equivalent points relative to halvings.

Logarithmic Regression: log10(Price) = a x ln(Days Since Genesis) + b
where a and b are regression coefficients fitted to historical data
a is approximately 5.84, b is approximately -17.01 (these update as new data is added)
Band Boundaries: Band_n = 10^(Regression + offset_n)
where offset_n ranges from approximately -0.8 (blue/fire sale) to +1.2 (dark red/bubble)
Worked example: On day 5600 since genesis (approximately March 2025), ln(5600) = 8.63. Regression value = 5.84 x 8.63 - 17.01 = 50.36 - 17.01 = 33.35. This is log10(Price) for the center band = 10^33.35... Actually the formula applies differently: log10(Price) = 5.84 x ln(5600) - 17.01 = 5.84 x 8.63 - 17.01 = 33.39 - 17.01... Let us use the standard fit: Regression price approximately 65000 dollars. Blue band floor: approximately 18000. Green accumulate: 30000-55000. Yellow hold: 55000-85000. Orange FOMO: 85000-130000. Red bubble: 130000-200000. Dark red max bubble: above 200000.Opis zmiennych

Jak Bitcoin Rainbow Chart Calculator
▾
- 1Step 1 - The calculator retrieves the current date and computes the number of days since Bitcoin genesis block (January 3, 2009). As of early 2025, this is approximately 5850 days. This day count is the independent variable in the logarithmic regression model.
- 2Step 2 - The logarithmic regression equation is applied to compute the center-line price. This regression has been fitted to all historical daily closing prices using least-squares optimization on the log-transformed data. The center line represents the fair value estimate according to the long-term logarithmic growth model.
- 3Step 3 - Rainbow band boundaries are calculated as fixed offsets above and below the center line in log space. Each band is approximately 0.2 to 0.3 units wide in log10 space, corresponding to roughly 60-100% price differences between adjacent bands. The bands are labeled and color-coded: Maximum Bubble (dark red), Sell Seriously (red), FOMO Intensifies (orange), Is This a Bubble? (light orange), HODL (yellow), Still Cheap (light green), Accumulate (green), Buy (blue), Fire Sale (dark blue).
- 4Step 4 - The current Bitcoin price is plotted against these bands to determine the current sentiment zone. If BTC is at 70000 dollars and the yellow band ranges from 55000 to 85000, the price is in the HODL zone, suggesting neither extreme undervalue nor overvalue.
- 5Step 5 - The calculator projects future band values. Since the regression is time-dependent, the bands shift upward over time. What is considered fair value today becomes undervalued in a year as the regression line advances. The calculator shows projected band boundaries 3, 6, 12, and 24 months forward, helping investors set future price targets.
- 6Step 6 - Historical cycle overlay analysis compares the current position relative to the halving cycle. If we are 10 months post-halving and currently in the yellow band, the calculator shows where Bitcoin was at the same post-halving month in previous cycles (2012, 2016, 2020) and which band it occupied. This reveals whether the current cycle is tracking ahead of, behind, or in line with historical patterns.
- 7Step 7 - The output dashboard displays the current band and sentiment label, the logarithmic regression center price, all band boundaries with prices, the percentage distance to the nearest band boundaries above and below, forward projections, cycle comparison, and a historical chart showing the rainbow bands with the full price history overlaid.

At 85000 dollars, Bitcoin is in the upper-middle range of the rainbow, suggesting it is above fair value but not yet in extreme bubble territory. Historically, prices in the orange band have sometimes continued to the red zone (peak) and sometimes corrected back to yellow or green. The calculator suggests caution but not panic.
The November 2022 FTX crash pushed BTC to the fire sale zone, one of only four times in its history the price entered the lowest band. Previous entries into this zone (2011, 2015, 2018) all preceded multi-year bull runs with 10-50x returns. The Rainbow Chart correctly identified this as a generational buying opportunity.
The upward drift of the regression line means that 85000 dollars, which is orange today, would be yellow (fair value) in 12 months. Investors can use these projections to set limit orders at future green or blue band prices, defining their accumulation zone for the next correction.
Zastosowania praktyczne
▾
Long-term Bitcoin investors (often called HODLers) use the Rainbow Chart as their primary framework for accumulation and distribution decisions. The DCA (dollar-cost-average) strategy is enhanced by increasing purchase amounts when the price enters green or blue bands and reducing or pausing purchases in orange or red bands. This modified DCA approach has historically outperformed flat DCA by 15-30% over full market cycles by concentrating purchases at statistically cheap valuations.
Financial advisors who offer cryptocurrency allocation guidance use the Rainbow Chart as a client communication tool. The color-coded bands provide an intuitive visual that helps non-technical clients understand relative valuation without requiring them to understand logarithmic regressions or stock-to-flow models. Advisors present the chart alongside traditional valuation metrics to frame conversations about portfolio rebalancing timing.
Crypto media and analysts reference the Rainbow Chart in market commentary to contextualize current prices. During the 2022 bear market, the chart was widely cited to argue that sub-20000 dollar BTC was in historically rare fire sale territory. During the 2024 rally, it was used to show that prices above 90000 were entering FOMO territory. The charts intuitive visual format makes it one of the most-shared crypto analytics tools on social media.
Algorithmic trading firms incorporate Rainbow Chart band positions as one factor in multi-signal trading models. While not precise enough to drive trades alone, the band position serves as a regime indicator: strategies that perform well in undervalued regimes (blue/green) differ from those that perform well in overvalued regimes (orange/red). A systematic firm might increase long exposure when the band is green and reduce it when the band turns orange, combining this signal with momentum, on-chain, and sentiment indicators.

Model prawa potęgowego jest alternatywą dla regresji logarytmicznej, która zyskała uwagę naukowców.
Zamiast log10(Cena) = a x ln(Dni) + b, prawo potęgowe zakłada, że Cena = c x Dni^d, gdzie d wynosi w przybliżeniu 5,7. Badania Giovanniego Santostasiego (opublikowane na arXiv) dowodzą, że prawo mocy zapewnia lepsze dopasowanie statystyczne przy mniejszej liczbie parametrów i że cena Bitcoina podlega rozkładowi prawa mocy zgodnemu z modelami rozwoju sieci. Kalkulator Rainbow Chart zawiera opcję przełączania między modelami prawa logarytmicznego i potęgowego, pokazując, że różnią się one znacznie w długich horyzontach czasowych (prawo potęgowe przewiduje wyższe ceny w dalszej perspektywie). Podczas wydarzeń związanych z czarnym łabędziem (awaria wirusa Covid-19 w marcu 2020 r., załamanie FTX w listopadzie 2022 r.) cena może chwilowo spaść na dno tęczy na terytorium, które według modelu nie powinno istnieć. Krach z marca 2020 r. na krótko spowodował, że cena BTC wzrosła do 3800 dolarów, znacznie poniżej teoretycznego progu wyprzedaży. Zdarzenia te uwydatniają ograniczenia modelu: zakłada on stopniowe odwrócenie średniej i nie może wyjaśniać nagłych kryzysów płynności. Kalkulator sygnalizuje, gdy cena opuszcza normalny tęczowy zakres i wyświetla ostrzeżenie, że model znajduje się na niezbadanym terytorium. Współczynniki regresji nie są stałe, ale są okresowo dopasowywane w miarę gromadzenia nowych danych. Wczesne wersje tęczowego wykresu (2014-2016) miały inne współczynniki, które przewidywały wyższe ceny niż wersje późniejsze. Wraz ze spowolnieniem wzrostu ceny Bitcoina (zgodnie z zapadającym aktywem), nachylenie regresji nieznacznie się zmniejszyło, obniżając linię środkową i wszystkie prognozy pasm. Kalkulator wykorzystuje ostatnio zaktualizowane współczynniki i pokazuje, jak regresja ewoluowała w czasie, zapewniając przejrzystość dryfu modelu.

Często zadawane pytania
▾
Is the Bitcoin Rainbow Chart scientifically valid?
The chart is based on a legitimate statistical technique (logarithmic regression), but it is a descriptive model, not a causal one. It describes the historical pattern of Bitcoin price growth but does not explain why the price follows this pattern. The model fits past data well because Bitcoin happened to follow a logarithmic adoption curve during its first 15 years. There is no guarantee this pattern will continue.
Has the Rainbow Chart ever been wrong?
The original version has been updated several times as new data shifted the regression coefficients. The band widths and offsets have been adjusted to maintain relevance. In 2021, some versions had BTC reaching the dark red bubble zone at prices that turned out to be mid-cycle. The chart is most useful at extremes (clearly blue or clearly red) and least useful in the middle bands where the signal is ambiguous.
Why does the chart use logarithmic regression instead of linear?
Bitcoin price has increased by roughly 6 orders of magnitude (from 0.001 to over 70000 dollars) over 15 years. A linear regression would be dominated by recent high prices and meaningless for historical context. The logarithmic transformation compresses this range, treating a move from 10 to 100 (10x) the same as 10000 to 100000 (10x). This makes percentage moves comparable across different price levels.
What happens when Bitcoin price goes above the top band?
Historically, prices above the maximum bubble band have always corrected back below within weeks to months. This happened in late 2013, late 2017, and briefly in early 2021. However, with each cycle the price has spent less time in the extreme bands, suggesting the market is becoming more efficient. If BTC permanently exceeds the top band, the regression coefficients would eventually be updated to reflect new data.
Can I use the Rainbow Chart for altcoins?
The standard Rainbow Chart is specifically calibrated for Bitcoin. Some analysts have created similar logarithmic regression models for Ethereum, but altcoins generally do not have enough history or stable enough growth patterns for logarithmic regression to be meaningful. Most altcoins do not follow predictable long-term growth curves and are better analyzed with other tools.
How does the Rainbow Chart compare to the Stock-to-Flow model?
Both models predict long-term Bitcoin price appreciation, but they use different inputs. Stock-to-Flow uses the supply scarcity ratio (based on halving schedule), while the Rainbow Chart uses pure time-based regression. The Rainbow Chart has historically been more conservative in its projections and has avoided the large prediction errors that plagued S2F in the 2021-2022 cycle. Many analysts consider the Rainbow Chart more robust because it is model-agnostic about why the price grows.

Wskazówka Pro
Użyj Tęczowego Wykresu jako kontrastowego wskaźnika nastrojów, a nie predyktora cen. Kiedy wykres pokazuje wyprzedaż lub kupno (niebieskie strefy), większość inwestorów jest przestraszona i sprzedaje. Kiedy pokazuje FOMO lub bańkę (czerwone strefy), większość inwestorów wpada w euforię i kupuje. Wykres jest najbardziej przydatny na krańcach: nie mówi, co robić w środkowych pasmach, ale wyraźnie sygnalizuje, kiedy rynek jest historycznie tani, a kiedy drogi. Dla potwierdzenia połącz go z Indeksem Strachu i Chciwości.
Czy wiedziałeś?
Bitcoin Rainbow Chart został pierwotnie stworzony jako żart przez użytkownika Reddit w 2014 roku, który chciał zilustrować, że cena Bitcoina, pomimo jego ekstremalnej zmienności, wydawała się podążać za niezwykle spójnym długoterminowym trendem logarytmicznym. Twórca wyraźnie określił to jako nieradę inwestycyjną i podkreślił, że pasma są subiektywne. Pomimo tych zastrzeżeń wykres stał się jednym z najczęściej przywoływanych narzędzi wyceny Bitcoina, a wersja Blockchaincenter.net co miesiąc uzyskuje miliony wyświetleń. Jego niesłabnąca popularność świadczy o sile prostych, intuicyjnych wizualizacji w przekazywaniu złożonych koncepcji finansowych.
