Bitcoin has long been recognized not just as a pioneering digital asset but as a financial phenomenon driven by predictable cycles. With the recent mining of the 19 millionth BTC—marking that 90% of the total 21 million supply is now in circulation—the cryptocurrency continues to draw intense analytical focus. One of the most visually compelling and historically accurate tools used to interpret Bitcoin’s price behavior is the rainbow chart. This logarithmic regression model highlights long-term trends, offering investors a macro-level view of bull runs, bear markets, and consolidation phases.
In this in-depth analysis, we explore how Bitcoin’s supply mechanics, halving events, and market dominance cycles align with the patterns visible on the rainbow chart since 2012. We’ll also examine current market positioning and what historical data suggests about future price movements.
How Bitcoin’s Supply Mechanics Shape Market Cycles
At the core of Bitcoin’s value proposition is its fixed supply cap of 21 million coins. Unlike fiat currencies, which can be printed indefinitely, Bitcoin’s scarcity is algorithmically enforced. New coins are introduced through mining, where block rewards are cut in half approximately every four years—a process known as the Bitcoin halving.
Each halving occurs after 210,000 blocks are mined. This block-based timeline creates a predictable cycle structure that has historically influenced price action:
- Blocks 1–70,000: Bullish phase — characterized by rapid price appreciation and growing public interest.
- Blocks 70,001–140,000: Bearish phase — marked by declining prices and reduced market sentiment.
- Blocks 140,001–210,000: Sideways or consolidation phase — prices stabilize before the next upward cycle begins.
Currently, we are in the post-2020 halving era, specifically within the bearish segment of this cycle. The block reward was reduced to 6.25 BTC per block during the third halving on May 11, 2020, setting the stage for the current market dynamics.

The Rainbow Chart: A Long-Term Price Guide
The Bitcoin rainbow chart plots price over time using a logarithmic scale, overlaid with colored bands that represent different valuation zones—from “cheap” (blue) to “overbought” (red). These bands follow a power-law regression curve, reflecting Bitcoin’s exponential growth trend over decades.
Since its first major run in 2013, Bitcoin has consistently followed this logarithmic path:
- Prices tend to bottom out in the blue and deep purple zones during bear markets.
- Bull runs push prices into the yellow and red zones before corrections occur.
- Each cycle reaches higher highs, reinforcing the long-term upward trajectory.
For example:
- In 2015, after the first post-halving dip, BTC bottomed around $200—deep in the “buy” zone.
- In 2019, following the 2018 crash, it rebounded from near $3,200, again aligning with historical support levels.
- The 2021 peak reached nearly $69,000, briefly touching the upper red band before correcting.
This repeated adherence to the rainbow model suggests strong statistical relevance, especially when combined with halving-driven supply shocks.
Market Dominance Cycles: Bitcoin’s Influence on Crypto
Bitcoin isn't just valuable on its own—it plays a central role in shaping the broader cryptocurrency market. Its market dominance, measured as BTC’s share of total crypto market capitalization, follows a cyclical pattern tied directly to halving eras.
Since 2016:
- During bullish phases, Bitcoin dominance rises to around 70% as capital flows into the most trusted asset.
- In bearish or altseason phases, dominance drops below 40%, indicating increased investor appetite for riskier altcoins.
This inverse relationship helps identify market sentiment:
- High BTC dominance = risk-off environment.
- Low BTC dominance = speculative altcoin rotation.
With dominance currently stabilizing above 50%, we may be nearing the end of the bear phase and transitioning toward renewed institutional interest in Bitcoin as a macro hedge.
Current Market Outlook: Where Is Bitcoin Headed?
We are now well into the third halving era (post-May 2020), situated within the expected bearish phase of the cycle. Historical patterns suggest that significant drawdowns are normal during these periods.
Key Metrics to Watch:
- Average drawdown per era: Approximately 80% from peak to trough.
- Cycle high (2021): ~$69,000.
- Implied low (80% drop): ~$13,800.
- Rainbow chart support crossover: Around $18,000.
Based on both technical regression models and historical precedent, the likely floor for this bear phase lies between $10,000 and $20,000, with $18,000 emerging as a strong confluence point between logarithmic support and cycle-based forecasting.
While short-term volatility persists due to macroeconomic factors like interest rates and regulatory developments, the long-term outlook remains anchored in supply scarcity and increasing adoption.

Frequently Asked Questions (FAQ)
Q: What is the Bitcoin rainbow chart?
A: The rainbow chart is a logarithmic price chart of Bitcoin overlaid with colored bands that indicate undervalued (blue/purple) and overvalued (red/yellow) zones based on historical trends.
Q: How accurate is the rainbow chart in predicting prices?
A: While not a precise forecasting tool, it has historically identified major tops and bottoms with notable consistency, especially when used alongside halving cycles and on-chain metrics.
Q: What does 90% of Bitcoin supply mined mean for price?
A: With 19 million BTC already in circulation, scarcity intensifies as fewer new coins enter the market. This reduced issuance, especially after each halving, tends to support long-term price appreciation.
Q: Are we still in a bear market for Bitcoin?
A: Yes. Based on block cycle analysis and price action since 2021, Bitcoin remains in a bearish phase. However, many indicators suggest we are approaching the final stage before the next accumulation and bull cycle begins.
Q: How do halvings affect Bitcoin’s price?
A: Halvings reduce the rate of new supply by 50%, creating upward pressure on price when demand remains constant or increases—a dynamic historically linked to major bull runs 12–18 months post-event.
Final Thoughts: Patience Pays in Bitcoin’s Long Game
Bitcoin’s journey since 2012 has been anything but linear—but beneath the volatility lies a remarkably consistent pattern. From halving-driven supply shocks to dominance cycles and logarithmic price trends, the data suggests that timing the market is less important than understanding its rhythm.
As we approach the potential bottom of the current cycle, investors would do well to remember that every previous bear market has eventually given way to a new all-time high. The mining of the 19 millionth coin isn’t just a milestone—it’s a reminder that Bitcoin’s scarcity is real, finite, and unfolding exactly as programmed.
