Bitcoin to Ethereum is the most watched crypto-to-crypto cross in the entire market. The ratio between the two is essentially a live read on whether the market is in “Bitcoin dominance mode” or “altcoin mode”, and it has spent the last decade oscillating between those two regimes in ways that define the broader crypto cycle. The converter at the top of this page shows you exactly how many ETH a given amount of BTC is worth right now.
How the BTC/ETH Cross Is Derived
There is no single canonical BTC/ETH price — there are many direct order books on centralised exchanges (Binance, Coinbase, Kraken, OKX), plus on-chain swap venues like Uniswap and Curve for WBTC against ETH, plus the implied rate from each coin’s USD price. All of these tend to agree to within a few tenths of a percent because arbitrage is fast and cheap. CoinGecko’s aggregate — which is what the converter above uses — takes both coins’ USD prices, divides one by the other, and publishes a single clean cross rate. It is the method used by almost every crypto data provider and it matches direct pairs closely.
Practically: if BTC is 100,000 USD and ETH is 3,500 USD, then 1 BTC is 100,000 / 3,500 ≈ 28.57 ETH. The reverse — 1 ETH in BTC — is 1 / 28.57 ≈ 0.035 BTC. That second number is the ETH/BTC ratio that every altcoin trader watches.
The ETH/BTC Ratio as a Market Indicator
The ETH/BTC ratio has a few distinct regimes worth knowing about:
ETH/BTC below 0.05 (“BTC dominance”). Bitcoin is leading the market. Money flowing into crypto is disproportionately going into BTC, either because of an ETF catalyst, a macro bid, a flight-to-safety moment inside crypto, or a narrative driver specific to Bitcoin. Altcoins broadly underperform in this regime. Typical early-cycle or late-bear environment.
ETH/BTC between 0.05 and 0.07 (“transition”). The ratio is rising but the market is unsure which way it wants to break. This is usually where BTC has made most of its move and speculation is starting to rotate into ETH and larger altcoins. Historically this has been the setup for broader altcoin outperformance.
ETH/BTC above 0.07 (“ETH leadership”). Ethereum is outperforming Bitcoin on a multi-week basis, which in the past has coincided with broader altcoin rallies — DeFi tokens, L2 tokens, infrastructure plays. This is usually the mid-to-late phase of a bull market. The ratio has historically peaked somewhere in the 0.08 to 0.10 range during the strongest ETH outperformance periods.
The ratio is not a mechanical indicator and it does not predict anything by itself, but it is one of the most useful one-chart reads on where the crypto market’s risk appetite actually is at any given moment.
1 BTC in ETH: What the Number Means
The live figure at the top of the page tells you how many ETH you could swap 1 BTC for at market rates right now. What it does not tell you is the actual net amount you would end up with after fees, which depends on the venue:
Centralised exchange direct pair. The cheapest option, typically. Binance, Kraken or OKX will let you market-order BTC/ETH for a taker fee of 0.1-0.26%, and the pair is deep enough that the spread impact on a retail-sized trade is negligible. Net cost: well under half a percent.
Routing through USD. On most US-accessible exchanges (Coinbase retail, Kraken for US customers) the direct pair may not exist in your jurisdiction. In that case you sell BTC for USD or USDT and then buy ETH with the proceeds, which doubles the fee and spread impact. Net cost: closer to 1%.
WBTC to ETH on-chain. On Uniswap or Curve you can swap WBTC (wrapped BTC) for ETH. This requires you to first bridge BTC to an EVM chain as WBTC (a custodial wrapping step via a service like BitGo or RenBridge), then execute the swap. Useful if you want to stay on-chain for other reasons, but the total cost including bridge fees and slippage on large sizes is usually higher than just using an exchange.
