Bitcoin's On-Chain Activity as a Leading Indicator of the Next Bull Cycle

Bitcoin's on-chain data has long served as a Rosetta Stone for understanding market sentiment and capital flows. As the 2023–2025 bull cycle unfolds, patterns in wallet behavior and transaction dynamics are offering a roadmap for investors seeking to time entry points. By dissecting metrics like exchange balances, the MVRV Z-Score, and HODL Waves, we can identify whether the market is in accumulation, distribution, or consolidation phases—and what that means for the next leg of Bitcoin's journey.

Exchange Balances: A Barometer of Investor Sentiment

Centralized exchange balances for Bitcoin have declined by 17% year-to-date, with approximately 2.5 million Bitcoin (12.6% of the circulating supply) now held on exchangesBitcoin’s Bull Run: Key Indicators To Navigate The 2025 Market Cycle^[1]. This trend reflects a structural shift: retail and institutional investors are increasingly moving assets to private wallets, either to signal long-term conviction in Bitcoin's value or to mitigate risks associated with centralized custodians. Historically, rising exchange balances have coincided with market peaks and profit-taking activityBitcoin’s Bull Run: Key Indicators To Navigate The 2025 Market Cycle^[1], making the current decline a bullish signal.

However, the story isn't one-dimensional. The average Bitcoin inflow per transaction on Binance has surged from 0.8 BTC in early 2024 to 13.5 BTC in late 2025Bitcoin On-Chain Data Signals Slowdown, Eyes on Fall 2025 Rally^[2], indicating a transition from retail-driven activity to whale and institutional dominance. Larger transactions suggest that high-net-worth actors are accumulating, a behavior often preceding sustained price appreciation.

MVRV Z-Score: Gauging Market Valuation

The MVRV Z-Score, which compares Bitcoin's market value to its realized value, currently sits below 3Bitcoin’s Bull Run: Key Indicators To Navigate The 2025 Market Cycle^[1]. This metric is critical: when the Z-Score exceeds 6, it historically signals overheated conditions and potential market tops. At its current level, Bitcoin remains undervalued relative to its realized value, suggesting there is significant room for appreciation before reaching “overbought” territory.

For context, during the 2017 and 2021 bull cycles, the Z-Score peaked at 6.5 and 7.2, respectivelyBitcoin’s Bull Run: Key Indicators To Navigate The 2025 Market Cycle^[1]. The 2025 cycle's slower pace—driven by spot ETF adoption and macroeconomic stability—has tempered volatility, but the underlying fundamentals remain intact. Investors should monitor the Z-Score closely; a move toward 5–6 could indicate a shift from accumulation to distribution.

HODL Waves: The Long-Term Holder's Playbook

The 1+ Year HODL Wave, which measures the proportion of Bitcoin held for over a year, has decreased in recent monthsBitcoin’s Bull Run: Key Indicators To Navigate The 2025 Market Cycle^[1]. This is a nuanced signal: while long-term holders (LTHs) typically accumulate during bear markets, a decline in the HODL Wave often precedes market peaks as LTHs begin to take profits. However, the current drop is less pronounced than in prior cycles, suggesting that LTHs are not aggressively liquidating.

This behavior aligns with broader capital flow patterns. The percentage of Bitcoin in profit has reached 90%, a level that historically precedes corrective phasesBitcoin On-Chain Data Signals Slowdown, Eyes on Fall 2025 Rally^[2]. Yet, unlike in 2017 or 2021, the market is not showing signs of panic selling. Instead, the 2025 cycle's prolonged nature—shaped by institutional adoption and macroeconomic tailwinds—has created a more measured environment.

Capital Flow Dynamics: From Retail to Whales

The shift in transaction sizes on platforms like Binance underscores a broader trend: retail participation is waning, while institutional and whale activity is surgingBitcoin On-Chain Data Signals Slowdown, Eyes on Fall 2025 Rally^[2]. This is not inherently bearish. In fact, larger transactions often indicate strategic accumulation by entities with deep capital and long-term horizons.

The Cumulative Volume Delta (CVD) across major exchanges has returned to neutral levelsBitcoin On-Chain Data Signals Slowdown, Eyes on Fall 2025 Rally^[2], signaling a reset in spot market bias. This is a critical inflection point: when CVD is positive, it indicates buyer dominance; when neutral, it suggests consolidation. At $111,000, Bitcoin appears to be consolidating, with buyers pausing to reassess risk-reward ratios. For investors, this creates a window to enter before the next upward thrust.

Timing Entry Points: A Framework for 2025

The 2025 bull cycle is distinct from its predecessors. The introduction of spot ETFs, macroeconomic stability (e.g., U.S. interest rate normalization), and institutional adoption have created a more gradual price appreciation curveBitcoin’s Bull Market: Latest On-Chain Data, Market Structure and Liquidity^[3]. This “slow burn” dynamic means that traditional entry points—such as post-halving rallies—are less relevant. Instead, investors should focus on on-chain signals:

1. Exchange Balances: A sustained decline in exchange-held Bitcoin indicates accumulation.
2. MVRV Z-Score: A Z-Score below 3 suggests undervaluation; a move toward 5–6 signals overheating.
3. HODL Waves: A sharp decline in the 1+ Year HODL Wave may precede a peak.
4. CVD Neutrality: A return to neutral CVD levels often precedes a breakout.

Conclusion: A Bull Cycle in the Making

Bitcoin's on-chain data paints a picture of a market in transition. While the 2025 cycle is slower and more institutionalized than prior cycles, the fundamentals remain robust. Exchange outflows, a low MVRV Z-Score, and whale-driven capital flows all point to a market in accumulation mode. For investors, the key is to avoid chasing price highs and instead use on-chain metrics to identify entry points during consolidation phases.

As the market approaches Q3–Q4 2025, the exponential phase of the bull cycle could materialize—if macroeconomic conditions remain stable. But even in a volatile environment, the data suggests that long-term holders are still accumulating, and the bull case remains intactBitcoin’s Bull Market: Latest On-Chain Data, Market Structure and Liquidity^[3].
