As of 19:00 UTC on July 28, 2025, the exchange rate of ETH/BTC was 0.0628 (Binance spot market data), meaning that one Ethereum is worth 0.0628 bitcoins. This figure has risen by 12.3% compared to the beginning of the year, but it is still lower than the peak of 0.085 during the bull market cycle in 2023 (TradingView historical chart). The key driving factor stems from the technological breakthrough after the Cancun upgrade of Ethereum: the transaction cost of the Layer2 network has dropped to an average of $0.001 (L2Beat monitoring), which has led to the total value locked (TVL) of its ecosystem reaching $41.2 billion, with an annual growth of 67% (DefiLlama statistics). In the current demand for eth and btc exchange, institutional arbitrage accounts for 43%. Among them, BlackRock’s ETH spot ETF saw a net inflow of 187 million US dollars in a single week, significantly reducing the discount space of ETH against BTC (Farside’s cash flow report).
The derivatives market intensifies exchange rate fluctuations. The open interest of ETH/BTC futures on the Deribit exchange reached 246,000 contracts, and the implied volatility index (IV) remained at 56%, 22 percentage points higher than the volatility of Bitcoin (Skew data analysis). When the daily fluctuation of the exchange rate exceeds 3%, the fluctuation range of the perpetual contract funding rate expands to ±0.12% (Bybit Risk dashboard). In May 2025, due to the US inflation data exceeding expectations, the eth btc exchange rate plunged by 5.2% within 6 hours, triggering a long liquidation worth 930 million US dollars (CoinGlass liquidation chart). Market makers’ spreads widen to 0.8% of the base exchange rate in extreme market conditions, which is 16 times higher than the 0.05% spread under normal liquidity (Kaio high-frequency Trading Research).
On-chain activities reveal the laws of capital rotation. Glassnode on-chain indicators show that in the past 90 days, the net outflow of ETH from centralized exchanges reached 3.4 million, while the net outflow of BTC during the same period was only 82,000, with a difference of 41.5 times in the outflow ratio. The staking rate of Ethereum rose to 27.3%, with an annualized yield of 5.2%, attracting $19.4 billion worth of ETH to participate (StakingRewards statistics), while the daily selling pressure of Bitcoin miners dropped to 550, hitting a four-year low (CryptoQuant miner reserve data). A notable case occurred in November 2024. During the first week of BlackRock’s ETH Trust’s listing, the institution enabled the eth btc exchange rate to appreciate by 8.7% in a single week through cross-market arbitrage, with the arbitrage profit margin reaching 3.1 times the benchmark (Bloomberg Hedge Fund analysis).
Macro variables are reshaping the correlation model. A 1% fluctuation in the US dollar index caused by the Federal Reserve’s interest rate decision would result in a change in the eth btc exchange rate that is 1.8 times that of the Bitcoin price (Morgan Stanley Correlation report). But technological upgrades will provide support: After the implementation of EIP-4844, the cost of Ethereum block space decreased by 83%, and the transaction throughput of ecosystem applications increased to 4,532 transactions per second (Ethereum Foundation benchmark test), while the processing speed limit of the Bitcoin Layer2 solution Merlin Chain was 2,100 transactions per second (Chainalysis network performance Evaluation). Current market forecasting models indicate that if Ethereum completes the Verkle Trees upgrade in 2025Q4, the exchange rate of eth btc may break through the resistance level of 0.071 (consensus prediction by CoinDesk analysts).
