Bitcoin vs Ethereum
Live side-by-side comparison with current values, changes, and key statistics.
Why This Comparison Matters
Bitcoin and Ethereum serve different purposes in the crypto ecosystem. Bitcoin is the store-of-value and monetary asset; Ethereum is the smart contract platform and DeFi backbone. When BTC leads ETH, the market favors safety and institutional adoption. When ETH outperforms, risk appetite is high and the market is pricing in DeFi growth and network activity.
Cross-Asset Analysis
Bitcoin (bitcoin spot price, the original cryptocurrency and macro risk-on barometer) and Ethereum (ethereum spot price, the leading smart contract platform token) are priced in separate markets, yet their co-movement tells macro desks something neither series reveals alone. Sector, style, and geographic dominance cycles each produce multi-year relative performance episodes between Bitcoin and Ethereum. Index construction choices inside Bitcoin and Ethereum, including weighting methodology and inclusion rules, create persistent tilts that show up in the spread.
Factor exposures embedded inside Bitcoin and Ethereum drive their relative performance, with growth-value, large-small, and domestic-international all surfacing in the spread. Across market regimes, the same pair reads somewhat differently. Idiosyncratic events in a concentrated peer, such as a single mega-cap earnings miss inside Bitcoin, can move the Bitcoin-Ethereum spread without broader factor signal.
Corporate action events, including buybacks or spin-offs affecting constituents of Bitcoin or Ethereum, can distort the spread relative to its intended factor tilt. Flows matter for the Bitcoin-Ethereum relationship: when one peer attracts more capital, it outperforms on demand pressure that often mean-reverts. Bitcoin and Ethereum occupy the same asset class, and the relative performance between them isolates the specific factor that distinguishes one from the other.
Use the Convex Risk Appetite Index (CRAI) as the regime filter when trading the Bitcoin-Ethereum pair; peer-level divergence is CRAI's most responsive signal.

Frequently Asked Questions
On what time frame is the Bitcoin-Ethereum comparison most useful?+
The most informative timescale for Bitcoin-Ethereum is where the macro signal dominates the noise: weekly data captures rotation dynamics without monthly noise from index reconstitution, making the weekly close the natural cadence for tracking the pair. Traders can use shorter horizons if they are sizing around events, but allocators should rely on the slower cadence.
What typically breaks the Bitcoin-Ethereum relationship?+
mega-cap specific events (earnings shocks, regulatory actions, index reconstitutions) produce peer-level dispersion that the broader asset-class story does not predict. When the usual relationship breaks, the question is always whether the break is temporary (a positioning or technical event) or structural (a regime shift), and that is usually clearer three to six months later than in real time.
How are Bitcoin and Ethereum historically correlated?+
Long-run correlation between Bitcoin and Ethereum varies by regime. Peers in the same asset class are highly correlated in direction, with the spread reflecting factor tilts and rotation dynamics. The correlation is not stable: it shifts with macro conditions, and the periods when it breaks down are often the most informative moments in the Bitcoin-Ethereum relationship.
What macro conditions drive divergence between Bitcoin and Ethereum?+
Divergence between Bitcoin and Ethereum typically arises from index reconstitution, mega-cap earnings surprises, or liquidity differences between the peers. When one asset's idiosyncratic drivers dominate, the spread moves in ways that the common macro story does not predict, which is usually a signal to look more carefully at the specific drivers at work in Bitcoin or Ethereum.
What is the relationship between Bitcoin and Ethereum?+
Bitcoin and Ethereum are connected through shared asset class exposure with different factor tilts. When the underlying asset class shifts, both respond, though with different sensitivities and at different speeds. The spread between Bitcoin and Ethereum captures the specific macro signal that flows through this relationship.
