Bitcoin Halving Countdown: Deep Dive into Miner Dynamics and Market Expectations

I. Introduction: The Countdown to the Fourth Halving

Bitcoin's fourth block reward halving is in its final countdown, expected to occur in late April 2025, Beijing time. At that point, the mining reward per block will drop from 6.25 BTC to 3.125 BTC. This event is not only a fundamental adjustment to Bitcoin's economic model but is also seen by the market as a catalyst for a new bull run. However, unlike previous halving cycles, the current macro environment, miner behavior, and market structure present new complexities. This report delves into three dimensions: miner dynamics, hashrate changes, and historical cycle comparisons, while offering an outlook for market trends over the next three months.

II. Miner Dynamics: Hoarding or Selling?

2.1 Historical Patterns of Miner Behavior

Looking back at the first three halvings (2012, 2016, 2020), miners typically reduced their external transfer volumes in the months leading up to the event, preferring to hoard rather than sell. According to CoinMetrics data, 90 days before the 2020 halving, the outflow of tokens from miner addresses dropped by about 30% compared to the average of the previous six months. The logic behind this behavior is that miners anticipate a supply squeeze post-halving to drive prices higher, thus they delay selling for greater profits. However, ahead of this halving, miner behavior has shown some divergence. Some large mining firms (e.g., Marathon Digital, Riot Platforms) disclosed in their late 2024 earnings reports that they have hedged some future production through futures to mitigate price volatility risk, while smaller miners, under operational cost pressures, have had to continuously sell Bitcoin to cover electricity and equipment maintenance costs. This coexistence of 'holding and selling' makes the net selling pressure from the miner community more complex than in previous cycles.

2.2 Hashrate Dynamics: Tidal Shifts and Power Competition

Bitcoin's total network hashrate hit an all-time high in 2024, exceeding 800 EH/s. After the halving, mining rewards are cut in half, meaning miners' revenue will instantly drop by 50% unless Bitcoin's price doubles to maintain breakeven. Currently, the breakeven point for most mining rigs falls within the price range of $45,000 to $65,000. According to F2Pool statistics, if the price fails to break $80,000 post-halving, about 15-20% of older mining rigs (e.g., the S19 series) face the risk of being shut down. This could lead to a short-term decline in total hashrate, triggering a mining difficulty adjustment (automatically lowering every 2,016 blocks). Historically, hashrate dropped by about 8% after the 2016 halving and about 4% after the 2020 halving. This time, with the arrival of the wet season in North America, some miners may migrate to cheap hydropower regions, sparking a new wave of hashrate migration. Additionally, the surge in AI computing demand (represented by Nvidia GPUs) is competing for power resources that were once available to miners, further increasing cost pressures. This competition may accelerate the phase-out of older mining rigs post-halving, pushing hashrate concentration toward top mining companies with access to low-cost power and efficient equipment.

III. Historical Halving Cycles and Price Impact: From Four-Year Bull Runs to Shorter Cycles

3.1 Theoretical Model of the Halving Effect

Bitcoin's total supply is capped at 21 million coins, and the halving mechanism creates a 'digital scarcity' by continuously reducing new supply. According to the widely used Stock-to-Flow (S2F) model, Bitcoin's scarcity after the halving will surpass that of gold. This model relatively accurately predicted price surges after the 2012, 2016, and 2020 halvings. However, it is worth noting that the S2F model is purely supply-based and ignores demand-side changes, leading to criticism during the 2022 market downturn.

3.2 Past Three Halvings and Price Performance

• First Halving (November 2012): Reward dropped from 50 BTC to 25 BTC. Price before halving was ~$12, rising to ~$1,000 within a year (an ~83x increase).
• Second Halving (July 2016): Reward dropped from 25 BTC to 12.5 BTC. Price before halving was ~$650, reaching ~$19,000 by December 2017 (an ~29x increase).
• Third Halving (May 2020): Reward dropped from 12.5 BTC to 6.25 BTC. Price before halving was ~$8,700, reaching ~$64,000 by April 2021 (an ~7x increase).

The trend is clear: the multiple of the cycle's price increase has diminished with each halving, but the absolute gains remain substantial. The 2020-2021 bull run was also fueled by institutional entry (e.g., MicroStrategy, Tesla) and global pandemic-era loose policies, resulting in a lower multiple but a higher peak price in absolute terms. After this halving, Bitcoin has already surpassed $100,000 in 2024, meaning the pre-halving price base is at a historical high. If historical patterns hold, another significant rally could occur over the next 12-18 months, but the multiple may further shrink to 2-3x.

3.3 Historical Performance Three Months Post-Halving

Looking at the short-term window after halvings: In the three months following the July 2016 halving, the price rose from $650 to about $750 (a ~15% increase), then entered a consolidation phase; after the May 2020 halving, the price rose from $8,700 to about $11,500 (a ~32% increase) in three months, also followed by range-bound trading. History suggests that the three months post-halving are typically not a period of price explosion, but rather a phase where the market digests the supply change and waits for new catalysts (e.g., ETF launches, regulatory progress). Therefore, over the next three months, Bitcoin may exhibit a pattern of 'initial decline followed by stabilization' or 'oscillating upward,' depending on macro liquidity trends.

IV. Market Outlook for the Next Three Months

4.1 Scenario 1: Macro and Halving Resonance (40% Probability)

If the Federal Reserve signals a rate cut in Q1 2025, combined with short covering by market makers post-halving, Bitcoin could steadily climb. Continued net inflows into spot ETFs (according to SoSoValue data, total assets under management in U.S. spot Bitcoin ETFs have exceeded $150 billion) would provide solid buying support. In this scenario, Bitcoin could break its previous high within two months post-halving and stabilize above $100,000 within three months.

4.2 Scenario 2: Miner Selling Pressure and Liquidity Contraction (35% Probability)

If miners are forced to sell coins post-halving due to deteriorating profitability, while the Fed maintains high interest rates and liquidity tightens, the crypto market could experience a 'sell the news' event. Similar to the modest pullback after the 2016 halving, historically, Bitcoin's maximum drawdown within one month post-halving has been about 20%. This time, some optimistic expectations may already be priced in (i.e., 'buy the rumor'), so the halving could trigger a short-term correction, with prices falling to the $80,000-$90,000 range before gradually recovering after miner selling is exhausted.

4.3 Scenario 3: Black Swan Event (25% Probability)

This includes, but is not limited to: U.S. government restrictions on crypto mining electricity use, exchange security incidents, or global financial risk events. Such shocks are unpredictable but require risk awareness. If one occurs, Bitcoin could drop to $70,000 or lower. However, given that Bitcoin has gradually become part of institutional asset allocation, extreme downside may be limited.

Overall, the most likely path over the next three months is: a modest pullback shortly after the halving, followed by a return to an upward trend driven by continued ETF inflows and expectations of a Fed policy shift. Investors should closely monitor miner on-chain outflows, hashrate changes, and macroeconomic data.

V. Conclusion: The Halving is a Starting Point, Not an End

Bitcoin's halving has never been a simple supply revolution; it is more like a self-optimizing machine that forces miners to improve efficiency through reward compression while signaling scarcity to the market. The fourth halving in 2025 occurs at a unique intersection of institutionalization, regulation, and globalization. Miner dynamics have evolved from a simple 'mine-and-sell' strategy to a sophisticated use of financial tools (options, futures, XOR lending). Market expectations have shifted from retail speculation to a true store-of-value narrative. In the next three months, the halving's short-term impact may be limited, but it plants the seeds for the next long-term upward cycle. As history has repeatedly shown: after Bitcoin's halving, the prelude to a new stellar rally often begins.
