BTC/ETH Market Move Explained: What Shaped Prices on August 3, 2026

Bitcoin and Ethereum opened the first Monday of August in a narrow range, with traders weighing a major hardware-wallet security incident, mixed U.S. spot ETF flows, and a Federal Reserve that is keeping rates on hold while Treasury yields drift higher. The result is a market that feels heavy rather than directional: Bitcoin is parked near the $63,000 handle and Ethereum is testing its July lows around $1,870. In this Bitcoin volatility explainer, we lay out the verified data, the drivers behind the move, and the technical levels that matter for the next 48 hours.

Snapshot: BTC and ETH Prices and Market Metrics

Data collected at 03:33 UTC on August 3, 2026 from CoinMarketCap, CoinGecko, Kraken, and TradingView spot feeds:

The numbers are deliberately shown as ranges because exchange spot feeds rarely match at the exact millisecond. Two details stand out. First, Bitcoin dominance is hovering near 59%, which means capital is still concentrating in the largest asset rather than rotating into altcoins. Second, Ethereum is underperforming on the BTC pair, with the ETH/BTC ratio sitting near multi-year lows. For a longer view of how these two assets move relative to each other, see our cryptocurrency volatility comparison.

Why Bitcoin and Ethereum Are Stuck in a Tight Range

1. The Coldcard Exploit Hit Self-Custody Confidence

On July 30, 2026, a firmware flaw in Coldcard hardware wallets was exploited in a 41-minute attack that drained approximately 1,082 BTC ($70.2 million) from about 1,196 wallets, according to Galaxy Research and BleepingComputer. The total estimated loss has since risen to around $88.6 million across multiple waves. The bug affected seeds generated on Coldcard Mk3, Mk4, Mk5, and Q models using firmware released since March 2021, when the devices used a deterministic software pseudorandom number generator instead of the intended hardware random-number generator. That reduced seed entropy to a level that made brute-force attacks practical.

Coinkite, the maker of Coldcard, has released patched firmware and advised users with potentially exposed seeds to generate new wallets and move their funds. The Bitcoin network itself was not compromised. The event did, however, remind the market that self-custody security is not automatic and that even hardware devices require verification.

2. ETF Flows Are Improving, but One Day Can Still Undo the Trend

U.S. spot Bitcoin ETFs ended July with a net inflow of $172.4 million, snapping a two-month outflow streak, according to data cited by Cointelegraph and FXLeaders. The July 31 session was ugly, with $265.4 million in net outflows, but the first four trading sessions of August saw renewed buying, including roughly $132 million on Friday. SoSoValue data also shows that rolling 30-day ETF flows have turned positive and now exceed 20,000 BTC, suggesting that institutional demand is rebuilding after the mid-year pullback.

For Ethereum, ETF flows have been more muted. BlackRock's iShares Staked Ethereum Trust (ETHB) has seen some inflows, but the broader Ether ETF complex is still trying to find a steady rhythm. The monthly picture is improving, but daily prints remain noisy and can flip quickly on risk-off headlines.

3. The Fed Is Holding Rates, but Yields Are Still Climbing

The Federal Reserve left the federal funds rate in the 3.50%–3.75% range at the July 28–29 FOMC meeting, with some members dissenting in favor of a quarter-point hike. Annual U.S. inflation was reported at 3.5% for the 12 months through June 2026, still well above the Fed's 2% target. The bigger worry for crypto is the bond market: the 10-year Treasury yield is near 4.74% and the 30-year yield has moved above 5.2%, its highest level in years.

Higher yields raise the opportunity cost of holding non-yielding assets like Bitcoin and Ethereum. When a long-term Treasury pays more than 5% with no drawdown, some institutional treasuries and risk managers reduce crypto exposure. The next FOMC meeting is scheduled for September 15–16, 2026, and the July vote was split enough that a September hike is not off the table.

4. August Seasonality and Weak Momentum

August has historically been a weaker month for Bitcoin, with more negative than positive monthly returns going back to 2013. A TD Sequential sell signal on the three-day chart near $65,000, combined with neutral-bearish momentum readings, is keeping the short-term bias tilted toward caution. The market is not crashing, but it is also not showing the kind of momentum that typically produces a clean breakout.

Technical Levels to Watch

Bitcoin

Bitcoin is trading below its 20-day, 50-day, 100-day, and 200-day moving averages. The 100-day simple moving average is near $68,750 and the 200-day simple moving average is near $71,125, both acting as dynamic resistance above current price. The 14-day RSI is near 45, a neutral-to-bearish zone. The ADX is near 15, which suggests a weak trend rather than a strong directional move.

  • Support: $62,800 – $62,900 is the immediate zone, followed by $62,200 and then $61,400. A sustained break below $62,200 would signal that sellers are gaining control.
  • Resistance: $63,500 – $63,550 is the first hurdle, followed by $63,900, $64,300, and $64,700. Reclaiming $65,000 is the first step toward a stronger recovery.

Ethereum

Ethereum is testing the lower end of its July range. The 14-day RSI is near the mid-point, around 50, which means the move is neither overbought nor oversold. The ETH/BTC ratio is near multi-year lows, confirming that Bitcoin is the stronger asset in the current environment.

  • Support: $1,800 – $1,820 is the key zone. A clean break below $1,800 opens the door to $1,750 and then $1,720.
  • Resistance: $1,950 – $2,000 is the first real ceiling. A move above $2,000 would flip the short-term bias back toward bulls.

Macro Context and What to Watch Next

The cross-asset picture is defensive. Long-duration Treasury yields are rising, the dollar is firm, and the Fed is keeping policy restrictive. The CLARITY Act, a U.S. crypto-market-structure bill, is facing a tight window before the August Senate recess, and its absence from the Monday schedule has added uncertainty.

Upcoming data to watch:

  • August 12, 2026: U.S. CPI report for July.
  • September 1, 2026: Vietnam's Decree 284 crypto-penalties rules take effect.
  • September 15–16, 2026: Next FOMC meeting.

FAQs

Why is Bitcoin price stuck near $63,000? The market is digesting a mix of improving ETF flows, a hardware-wallet security incident, rising Treasury yields, and historically weak August seasonality. The result is consolidation rather than a clear trend.

Is the Coldcard exploit a flaw in Bitcoin itself? No. The exploit was a firmware bug in Coldcard hardware wallets. The Bitcoin network and protocol were not compromised. Users who generated seeds on affected firmware should create new wallets and move their funds.

What does a Fed rate hold mean for crypto? A steady rate keeps borrowing costs elevated and makes fixed-income assets more attractive relative to non-yielding crypto. If the Fed moves toward a hike in September, risk assets could face additional pressure.

Is Ethereum still in an uptrend? Ethereum is testing a key support zone near $1,800. A break below that level would weaken the bullish structure, while a move above $2,000 would suggest the uptrend is intact. ETH is currently underperforming BTC.

What is the next big event for Bitcoin? The short-term catalysts are the August 12 U.S. inflation report, the September 16 FOMC decision, and whether BTC can hold the $62,800–$63,500 support zone. Traders are also watching the CLARITY Act timeline.
