With Bitcoin prices hovering above the $55,000 zone, the question on every trader's mind is: when will this bull run end? A myriad of charts, models, and indicators have been proposed by analysts and enthusiasts, each claiming to provide insight into the cycle's peak. Yet, as history shows, none are infallible. This article explores the most popular forecasting methods currently in use, their underlying logic, and their inherent limitations.
1. The Classic Bull Cycle: Around 518 Days
In a comprehensive analysis published in April 2021, well-known analyst Rekt Capital noted that a typical Bitcoin bull run lasts approximately 518 days. By comparing two post-halving market cycles, he found that the bottoming phase before a halving averages 546 days, while the rally from the halving to the cycle top averages 518 days. This timeframe serves as a benchmark for many investors.
2. The Three-Wave Theory: HODL Waves and Realized Cap Heatmaps
The popular Twitter account Bitcoin Archive shared a Glassnode chart of realized cap HODL waves, suggesting that Bitcoin bull markets typically have three waves. According to this view, the first wave has already formed and 'hot money' has cooled down, paving the way for another surge. However, analyst Cryptovizart countered that institutional FOMO (Fear Of Missing Out) has extended the first wave far beyond previous cycles, potentially invalidating the three-wave pattern.
3. Composite Index: The Crypto Bitcoin Bull Run Index (CBBI)
YouTuber Colin Talks Crypto developed the CBBI, an average of 8 to 11 different Bitcoin metrics (including MVRV Z-Score, Puell Multiple, and Reserve Risk) that produces a score from 0 to 100. The closer the score gets to 100, the closer the market is believed to be to a price top. On May 10, 2021, the CBBI stood at 71, indicating that while the market is in a late bullish phase, it has not yet reached extreme overvaluation.
4. Other Common Tools: MA 200 Heatmap, Google Trends, and Derivatives Markets
Data provider Coincharts uses a combination of tools, including the MA 200 Heatmap (based on the 200-week moving average), Google Trends, and HODL waves, to assess the current position within the bull run. They note that it has been 143 days since Bitcoin broke its 2017 all-time high (~$20,000). However, they caution that determining the exact peak is extremely difficult. Meanwhile, some participants now rely on Bitcoin derivatives markets (futures and options) to gauge short-term sentiment, while others point to the upcoming Taproot upgrade or continued institutional adoption as fundamental catalysts that could keep the rally alive.
5. No Perfect Tool, But The Quest Continues
Whether it's the Stock-to-Flow (S2F) model, logarithmic growth curves, golden ratio multipliers, or even tarot cards, each market participant seeks their own 'holy grail' to predict price direction. As the original article states: no tool or model is perfectly accurate. Bitcoin's future is shaped by countless unpredictable factors — regulatory shifts, macroeconomic conditions, technological breakthroughs, and market sentiment. Nevertheless, one thing is certain: market participants will always try to forecast what lies ahead using every available resource.
In summary, where is the current bull run? Different indicators offer different answers. Investors should understand the limitations of each model and always practice risk management, because the true market top is only clear in hindsight.
