Welcome to ARC
ARC gives you a data-driven Bitcoin fair value estimate. No noise, no opinion. Just a model-based price target built on 14 years of on-chain data and macro factors. Here's how to read it.
What you're looking at
Time horizons
3M
Short-term
Heavily influenced by macro conditions: ETF flows, Fed policy, and risk sentiment. Most volatile estimate. 70% macro, 30% fundamentals.
1Y
Medium-term
Balanced between macro and fundamentals. Better signal for cycle positioning. 50% macro, 50% fundamentals.
5Y
Long-term
Macro effects fade to near zero. Price is dominated by Power Law trend and adoption. 15% macro, 85% fundamentals.
Key concepts
Power Law
Bitcoin has followed a log-log power law trend since 2012 (R²=0.965). The model uses this trend as a long-run anchor. When spot is far below the trend, history says it reverts upward.
MVRV
Market Value to Realised Value. Compares what BTC trades at versus the aggregate on-chain cost basis. Below 1.74 (the historical median) = most holders near breakeven = accumulation zone. Above 3.7 = distribution zone.
PL Z-score
How many standard deviations spot is above or below the Power Law trend. Below -1s has historically been the strongest accumulation zone. Above +1.5s has historically preceded corrections. Currently shown in the topbar.

Base scenario output
The three anchor models (Power Law, SPI+ADI, MVRV) each produce an independent fair value estimate. These are blended by horizon-specific weights. The result is multiplied by a macro factor, which is a Kalman-filtered linear combination of 15 z-scored macro variables. At 3M horizons the macro factor dominates (70%). At 5Y it fades to near zero (15%) as macro conditions mean-revert and fundamentals take over.

Not financial advice
ARC is a quantitative modelling tool. The model explains price using historical relationships - it does not predict the future. Out-of-sample directional accuracy is 58-65%. Black swan events (exchange collapses, regulatory bans, global recessions) are not modelled. Use this as one analytical input, not as a trading signal.

How to read: PL Central is the pure Power Law trend price at each date. Bear/Base/Bull FV is the Composite Anchor (PL + SPI+ADI + MVRV) multiplied by the factor premium/discount at each Kalman beta percentile. At 5Y, factor contribution approaches zero and Base FV converges toward the anchor.

The Power Law Z-score measures how far the current BTC price sits above or below the long-run Power Law trend in log-space. The trend is calibrated on 14 years of daily data (R²=0.965). A Z below -1 has historically been a strong accumulation zone, meaning price is more than one standard deviation below trend. The current reading of -0.86 puts BTC in "Undervalued" territory. Historically when Z was below -0.5, BTC returned a median of +140% over the following 12 months.

MVRV (Market Value to Realised Value) compares what the market values BTC at vs the aggregate on-chain cost basis of every coin. When MVRV = 1.0, the average holder is breakeven. Below 1.74 (historical median) means most holders are near or below their cost basis, which is historically an accumulation zone. At 1.297, the average holder is +30% in profit, but still well below the median cycle reading.

The SPI (Supply Pressure Index) measures how tight the liquid BTC supply is - specifically, how much is available to trade after ETF absorption and miner retention. The ADI (Adoption Demand Index) measures demand via active addresses, stablecoin velocity, and Lightning Network capacity. Combined regression R²=0.689. When ETFs absorb more BTC daily than miners produce (current: ~970 BTC/day ETF vs ~450 BTC/day new supply), the SPI enters negative territory, indicating a structural supply crunch.

How the Model Works
THE MASTER EQUATION
BTC Fair Value = Anchor
x exp(S beta·Z)
x exp(S beta·Z)
The model has two engines. The Anchor is what Bitcoin is fundamentally worth - a weighted blend of three models based on supply scarcity, adoption, and on-chain cost basis. The Factor multiplier is how much the current macro environment should push that price above or below anchor. exp(positive sum) = premium. exp(negative sum) = discount.
ANCHOR - 3 MODELS BLENDED
Power Law (25%)
Time-based trend · R²=0.965
SPI + ADI (40%)
Supply crunch + adoption · R²=0.689
MVRV (35%)
On-chain cost basis · mean-reversion
Each model captures a different dimension of value. PL is pure time. SPI+ADI captures real supply/demand balance including ETF flows. MVRV captures where we are in the market cycle relative to aggregate holder cost. MVRV reverts gradually (9-month half-life) from its current level of 1.297 toward target, not in a single jump.
FACTORS - 5 BLOCKS, 17 SIGNALS
Block 1 - Monetary: Fed cuts, real yield, M2, yield curve
Block 2 - Risk: SPX, VIX, DXY, HY spreads
Block 3 - Crypto: ETF flow, OI, funding, exchange reserves
Block 4 - On-Chain: LTH accumulation, SOPR, options skew
Block 5 - Regulatory: Regime, sovereign adoption
Each factor is normalised to a z-score vs its historical average. Z > 0 = better than normal for BTC = premium. Betas are estimated using a Kalman Filter, which lets them evolve over time - so the ETF flow beta, which did not exist before Jan 2024, is now the largest single factor in the model.

Fundamentals win
At short horizons, macro factors dominate - real yields, equity markets, and ETF flow movements drive price. Over 5 years, all macro factors mean-revert toward zero and the anchor (Power Law time trend, MVRV cycle position, supply dynamics) is almost entirely responsible for the price target.

Limitations
This is not a trading signal. The model gives a structural fair value estimate. BTC can trade below fair value for months or above it for longer. The model explains price; it does not predict timing.
Black swans are not modelled. FTX collapse, COVID crash, regulatory bans - any sudden event can gap the price far outside any corridor. The bear floor ($45K at 3M) is a model floor, not a guarantee.
The Power Law has no mechanism. It is purely empirical - Bitcoin has followed this log-log trend since 2012. It may stop. The R²=0.965 is impressive but 14 years of data is a short history for a power law claim.
OOS accuracy is 58-65%. The factor model predicts direction correctly about 60% of the time out-of-sample. Better than a coin flip, worse than what headlines might imply. Use it as one input, not the only one.

ACCUMULATE
BTC Price vs Fair Value Deviation: Daily Heatmap (2022-2026)
Fear & Greed: What to Watch
EXTREME FEAR (0-25)
Historically the strongest accumulation zone. Most holders are capitulating. On-chain data typically shows: SOPR below 1.0 (selling at a loss), LTH accumulation rising, exchange outflows. BTC returned a median of +180% in the 12 months following extreme fear readings.
Key drivers: macro fear, liquidation cascades, negative news flow
NEUTRAL (45-55)
Market in equilibrium. Neither fear-driven selling nor euphoric buying. Often seen during consolidation after sharp moves. Watch for: direction of funding rates, ETF flow trend, and whether open interest is building. Breakout direction from neutral often signals the next 30-60 day trend.
Key drivers: macro data, Bitcoin dominance shifts, funding rate direction
EXTREME GREED (75-100)
Historically a near-term caution zone. Retail FOMO dominates, leverage is elevated, funding rates spike. Watch for: PL Z-score above +1.5s, MVRV above 3.7, negative ETF outflows. Corrections of 30-50% have occurred within 3 months of sustained extreme greed.
Key drivers: retail inflows, leverage build-up, positive news saturation
WHAT MOVES FEAR & GREED
Price momentum (25%)
30-day vs 90-day price change. Rising prices push greed.
Market volume (25%)
Trading volume vs 30-day avg. High volume + rising = greed.
Social sentiment (15%)
Twitter/Reddit mentions and sentiment scoring.
Dominance (10%)
Rising BTC dominance = fear (flee to BTC safety). Falling = greed (risk alts).
Google Trends (10%)
"Bitcoin" search volume. Spikes = retail FOMO = near greed peaks.
Volatility (25%)
High unexpected volatility = fear. Low calm volatility = greed building.
