Top Story
A hawkish Jackson Hole speech triggered a broad crypto de-risking move on August 28. Bitcoin fell below $78,000, while Ethereum slipped below $2,450. Traders linked the move to higher rate-hike expectations.
The decline followed a strong rally and resistance near $81,000 to $82,000 for Bitcoin. A $6.4 billion options expiry also added volatility. Preliminary reports cited $82.54 million in futures liquidations, while social-media estimates placed total liquidations near $488 million. The larger figure is not independently confirmed by the derivatives data available.
The market reaction was broad. Bitcoin fell 3.16% to $77,465.49 on $34.51 billion in volume. Ethereum dropped 2.74% to $2,434.95 on $20.22 billion. Solana fell 3.91% on $6.08 billion, while BNB, XRP, Dogecoin, and Chainlink also closed lower.
ETF demand also weakened. Spot Bitcoin ETF flows were approximately negative $105.6 million on August 28, according to a preliminary report. That followed nine straight sessions of inflows, including $242.3 million for Bitcoin products and $235 million for Ethereum products on August 27. The next official flow data will show whether the reversal was temporary or marks a broader cooling in institutional demand.
Major Price Moves
Market Overview
The top two coins by market capitalization both declined. Bitcoin ranked first at $77,465.49, down 3.16% on $34.51 billion in 24-hour volume. Ethereum ranked second at $2,434.95, down 2.74% on $20.22 billion. The heavy turnover confirms that the move affected the most liquid markets, rather than reflecting only thin altcoin trading.

Relative strength was concentrated in a few names. Zcash, Rain, and Monero were the only clearly positive top-20 assets in the supplied market snapshot. TRON was nearly unchanged at negative 0.01%.
Hyperliquid also held up better than most large caps. It fell 2.50%, less than Bitcoin, Ethereum, Solana, and Chainlink, while maintaining $1.36 billion in volume.
The supplied results do not include the underlying full 150-coin rows or a verified total-market-cap series. A total crypto market-cap chart and a precise Bitcoin dominance chart therefore cannot be calculated without fabricating data. The previously supplied “84.7%” figure was not a valid dominance calculation.
Other Key Events
SEC proposes crypto-specific offering exemptions
The SEC proposed “Regulation Crypto Assets,” which would create two exemptions for certain crypto-asset investment-contract offerings. One would cover offerings of up to $5 million over four years. Another would cover up to $75 million during each 12-month period.
The proposal also includes a conditional safe harbor from the term “investment contract” for certain assets. It is not final law. Separate custody-rule work, identified as RIN 3235-AN46, remained at the proposed-rule stage after entering White House review on August 25. Political uncertainty also continues around the CLARITY Act because of SEC and CFTC vacancies.
ETF momentum broadens, then reverses
Regulated-product demand was strong earlier in the week. Weekly inflows reached $1.92 billion for Bitcoin ETFs and $697 million for Ethereum ETFs, for a combined $2.62 billion. Solana ETFs added $60.91 million, while Hyperliquid ETFs attracted $24.42 million in the August 27 report.
A Bitwise fund also became the first Solana ETF to reach $1 billion in assets under management. Bitwise separately filed a preliminary prospectus for a NEAR ETF on August 28. The filing does not mean approval or trading authorization.
The negative preliminary Bitcoin flow figure for August 28 matters because it followed nine sessions of inflows. Social-media discussion also focused on concentrated demand, with claims that BlackRock’s IBIT captured 115% of August 27 net inflows while Fidelity and Grayscale experienced combined outflows above $110 million. Those social claims were not independently verified in the supplied official data.
Reported Coldcard exploit raises self-custody concerns
A law-firm briefing reported that public analysis attributed the Coldcard exploit to 1,789.28 BTC stolen across 8,865 addresses. Approximately 1,561 BTC reportedly remained unspent at publication. These figures describe reported estimates, not a newly confirmed incident on August 28.
X discussion cited a firmware seed-generation vulnerability dating to 2021 and estimated effective entropy between 40 and 72 bits. Galaxy Research reported a honeypot sweep involving five dice rolls added as entropy. Alex Thorn said the attackers remained active. The retrieved material did not establish claims of intentional compromise or developer responsibility.
Ledger also released Ethereum app version 1.22.3 on August 25 to address vulnerabilities LSB-024 and LSB-025. Ledger said no user had been hacked and described the demonstration as a laboratory reproduction using outdated software.
In Brief
- MAP Protocol reported new ERC-20 and BEP-20 versions for MAPO, while stating that total supply remains 10 billion. Its August update cited 580,405 active addresses and more than 3.9 million cross-chain transactions. The publication date and causal link to the rally were not confirmed.
- No current catalyst was found for the Aavegotchi surge. The move reached 105.92%, but available market coverage did not identify a fresh partnership, listing, unlock, exploit, or regulatory action.
- No August 28–29 catalyst was found for Helium. Official items located were dated August 27 or earlier. The token rose 34.72%.
- No confirmed negative event was found for Cash Cat or SPX6900. Coinbase reported zero recent SPX6900 news articles in its available feed.
- No current catalyst was found for LayerZero. Its next documented major unlock is September 19, 2026, worth approximately $25.28 million. That future event does not explain the August 28–29 decline.
- Social chatter around Zcash, Helium, and Aavegotchi was limited. SPX6900 and Cash Cat posts focused mainly on claim portals. The activity looked promotional, not like broad conviction.
- The available search results did not confirm a major protocol upgrade launching specifically on August 28–29. An Arbitrum ArbOS 61 summary cited a fourfold increase in Stylus contract capacity to 96 KB, but activation during this window was not established.
Derivatives and Sentiment
The Crypto Fear & Greed Index stood at 67, classified as Greed. The seven-day reading declined by three points. The 30-day average was 43, classified as Fear, while the 30-day high was 74. Sentiment therefore remained optimistic, but momentum had stalled near the upper end of the recent range.
Open interest declined across every asset with available data. The move indicates leverage reduction rather than fresh derivatives expansion.
| Asset | Current Open Interest | Two-Day Change | Trend | |
|---|---|---|---|---|
| BTC | $54.11B | -$1.63B, -2.92% | Stable | |
| ETH | $32.27B | -$1.10B, -3.29% | Stable | |
| SOL | $6.99B | -$106.52M, -1.50% | Stable | |
| DOGE | $1.33B | -$103.47M, -7.21% | Decreasing | |
| XRP | Unavailable | Unavailable | API error |
Combined open interest for Bitcoin and Ethereum was approximately $86.38 billion. Dogecoin recorded the sharpest contraction, down 7.21%, showing the largest reduction in reported leveraged participation.
Funding rates and liquidation totals were unavailable because the derivatives API returned “Too Many Requests.” No long-versus-short liquidation split, funding anomaly, or unusual cascade can be confirmed from the supplied derivatives data.
What to Watch
- Bitcoin at $77,000 and $75,000: A break below $77,000 would put the $75,000 area in focus. The next session’s spot volume will show whether the decline continues.
- Ethereum at $2,400: The market identified $2,450 as a pivot, with $2,435 and $2,400 as nearby support levels. A close below $2,400 would deepen pressure on staked ETH products.
- ETF flows after August 28: Verify whether the preliminary negative $105.6 million Bitcoin flow becomes an official outflow and whether the nine-session inflow streak has ended.
- Zcash near $800: ZEC gained 1.29% to $794.68 on $2.09 billion in volume. Follow-through above $800 would confirm continued relative strength.
- LayerZero supply schedule: The next documented major unlock is September 19, 2026, valued at approximately $25.28 million. It is not a current catalyst, but it is the next identified supply event.
- Coldcard wallet activity: Research accounts reported continued attacker activity and a transaction involving 0.00043224 BTC at block 964,481. Users with potentially affected devices should verify firmware and wallet-security guidance before signing transactions.
