Is the Bitcoin Bull Market Over? Key Indicator Signals a Shift
The crypto market thrives on narratives, but cycle turns are ultimately about data. As we move through 2025, one market-tested signal stands out for gauging whether Bitcoin’s bull phase is intact or stalling: the Bull Market Support Band (BMSB) on the weekly chart. Used alongside ETF flow dynamics and on-chain valuations, it offers a high-signal way to assess if momentum is rotating from expansion to distribution.
The Key Indicator: Bitcoin’s Bull Market Support Band
The Bull Market Support Band is the zone formed by the 20-week simple moving average (20W SMA) and the 21-week exponential moving average (21W EMA). Historically:
- Above and respecting the band: trend expansion and “buy-the-dip” conditions
- Below with rejections at the band: distribution, deeper drawdowns, or bear phases
How to read it:
- Weekly closes: One close below the band can be noise; two or more, followed by rejection on a retest, increases the probability of a regime change.
- Slope and breadth: A flattening or downward-sloping band often precedes prolonged ranging; a sharply rising band supports trend continuation.
- Confluence: Add the 200-day moving average (200DMA). Sustained price below both the BMSB and the 200DMA has preceded past cyclical drawdowns.
Why it works in the ETF era
Since U.S. spot Bitcoin ETFs launched in January 2024, weekly trend levels matter even more. Large allocators scale in/out near long-term moving averages, reinforcing these levels as liquidity magnets. The BMSB remains effective because it blends trend, liquidity behavior, and investor psychology into one weekly signal.
ETF Flows, Liquidity, and Macro: Validating the Signal
The BMSB is strongest when validated by flow and liquidity metrics:
- Spot ETF net flows: Persistent net inflows support dips; sustained outflows or drying inflows around a BMSB breakdown raise distribution risk.
- Perp funding and basis: Extended positive funding with falling price implies long-side fragility; neutral/negative funding during bounces hints at healing.
- Open interest (OI): Elevated OI relative to market cap amplifies liquidation cascades during BMSB breaks; OI resets can form bases.
- Dollar and rates: A firming DXY and rising real yields tend to pressure crypto risk; easing conditions can rescue borderline trend tests.
| Indicator | What to Watch | Bullish Read | Shift/Bearish Read |
|---|---|---|---|
| BMSB (20W SMA / 21W EMA) | Weekly closes and retests | Closes above; successful retests | Multiple closes below; rejections |
| 200DMA | Confluence with BMSB | Price above, rising slope | Price below, flattening or falling |
| Spot ETF net flows | Daily/weekly sums | Consistent net inflows | Sustained outflows or thin inflows |
| Funding/basis | Cost of leverage | Moderate, stable | Persistently high then flipping |
| On-chain MVRV/NUPL | Valuation heat | Neutral to modestly elevated | Extended euphoria, then rollover |
On-chain and Miner Signals That Complement the BMSB
On-chain analytics add context to a potential shift:
- MVRV and MVRV-Z: High MVRV that starts trending down while price loses the BMSB often marks distribution. Neutral MVRV with a reclaim of the band supports continuation.
- NUPL: A transition from “Euphoria/Greed” to “Belief” during a BMSB loss raises the odds of a deeper cooling period.
- Puell Multiple and miner revenue: Post-2024 halving, miner margins rely more on price and fees. Rising miner sell pressure into a BMSB breakdown can accelerate downside; easing sell pressure helps form floors.
- Stablecoin liquidity: Expanding stablecoin market caps tend to precede fresh spot demand; contraction during a BMSB break weakens dip bids.
Scenario Analysis for 2025
- Range-bound distribution
- Setup: Multiple weekly closes below the BMSB, flat 200DMA, mixed ETF flows.
- Implication: Chop-heavy market; rotational alpha in BTC vs. majors and selective web3 narratives.
- Deeper cyclical drawdown
- Setup: BMSB lost and retested as resistance, 200DMA lost, sustained ETF outflows, rising real yields.
- Implication: Focus on risk management; historical drawdowns of 25-40% from local highs are not unusual mid-cycle.
- Renewed trend continuation
- Setup: Reclaim of BMSB with strong weekly close, positive ETF flows, neutral funding, improving stablecoin supply.
- Implication: Higher-probability dip buys; leadership rotates back to BTC, then high-quality L2 and infrastructure plays.
Practical Takeaways for Crypto Traders and Builders
- Anchor to the weekly: One candle does not make a regime. Wait for weekly confirmation above/below the band.
- Use flow + trend confluence: Combine BMSB status with ETF flows and 200DMA to reduce false signals.
- Mind leverage: Elevated OI and frothy funding into a BMSB test often precede swift liquidations.
- Watch liquidity rails: Stablecoin supply trends and exchange spot volumes inform the strength of any reclaim.
- Builders: Plan runway and releases assuming range volatility. Products with real fee generation and L2 cost advantages outlast sentiment shifts.
Conclusion: Is the Bull Market Over?
No single metric can call the cycle top, but the Bull Market Support Band remains a reliable, public, and timely indicator. A sustained loss of the BMSB-especially with weak ETF inflows, a falling 200DMA, and cooling on-chain metrics-signals a shift from easy trend-following to defense and selectivity. Conversely, a decisive reclaim with supportive flows argues the bull phase is intact. In 2025, let weekly structure lead, use flows to validate, and adapt faster than the narrative.
