Ether crossed $300 on July 25, 2020, as an Ethereum-led rally widened the performance gap between the two largest cryptocurrency markets.
Coinbase Exchange data show that ETH-USD opened the UTC session at $279.66, traded as high as $310 and closed at $305.66. Compared with Coinbase’s July 24 close of $279.59, that was a 9.3% close-to-close increase. The exchange recorded approximately 245,086 ETH of base-asset volume during the July 25 UTC candle.
Bitcoin advanced more slowly on the same venue. Coinbase’s BTC-USD market rose from a July 24 close of $9,551.21 to $9,711.33 on July 25, a 1.7% increase. Ether’s relative strength therefore marked more than a broad market bounce: capital and attention were concentrating around Ethereum and the applications being built on it.
What the market data establish
The verified development is narrow but significant. Ether exceeded $300 and completed the July 25 UTC session above that threshold on Coinbase. The 9.3% figure is Coinburn’s calculation from consecutive Coinbase daily closes, rounded to one decimal place. The corresponding bitcoin calculation uses the same venue, quote currency and UTC boundaries.
Those measurements are not a consolidated global close. Cryptocurrency markets trade continuously, and prices can differ across exchanges. Coinbase also warns that its historical-candle endpoint can return incomplete information where trading data are absent. The figures establish activity on Coinbase’s ETH-USD and BTC-USD order books; they do not represent every venue or prove that any single news item caused the move.
DeFi supplied the immediate context
The principal contemporaneous explanation was the expansion of decentralized finance, or DeFi, on Ethereum. Lending markets, decentralized exchanges and incentive programs were generating additional demand for tokens and Ethereum block space. Reporting published earlier in the week, citing Coin Metrics, connected that activity with rising transaction fees and heavily utilized blocks.
That evidence supported a demand narrative, but it also exposed a constraint. More use could increase demand for ether and Ethereum-based assets while making transactions more expensive. The July 25 price move should therefore be read as a market response occurring alongside stronger network activity—not as proof that Ethereum had solved its capacity limitations or that DeFi valuations were sustainable.
The distinction mattered because many DeFi tokens had short trading histories, liquidity-mining rewards could encourage temporary deposits, and measures such as “total value locked” were sensitive to token prices and accounting methodology. Rising ether prices could increase the dollar value assigned to collateral even without an equivalent inflow of new assets.
Protocol expectations were also in view
Ethereum’s development roadmap provided a second source of attention. On July 23, the Ethereum Foundation announced that the community-operated Medalla multi-client testnet had an earliest launch time of August 4, subject to reaching its minimum validator condition. The announcement described Medalla as a step beyond earlier developer-run networks, not a production-network upgrade.
That distinction was material on July 25. A scheduled testnet demonstrated development progress and gave operators a near-term milestone, but it did not guarantee a successful launch, establish a mainnet date or immediately increase Ethereum’s transaction capacity. Treating the testnet timetable as certainty would have exceeded the contemporaneous evidence.
Later context
Reporting on July 26 recorded ether extending the move to approximately $316 and bitcoin briefly passing $10,000. Those subsequent prices help confirm that July 25 began a broader weekend breakout, but they were not part of the July 25 Coinbase UTC closing calculation and should not be projected backward into the event-day record.
