Bitcoin Grinds Toward Best August Since 2017 as ETHA Call-Skew Leads Options Tape

Ethereum's ETHA is showing the day's cleanest options signal, with a 0.321 put-to-call volume ratio pointing to concentrated call demand as spot ETH trades at $2,467, up 2.0% over 24 hours. Bitcoin holds $78,584 with a 1.7% intraday range, on track for its strongest August since 2017 despite a quiet macro tape.

Market Pulse

Spot prices sit broadly higher into the New York lunch hour. Bitcoin trades at $78,584, up 1.15% over 24 hours with a 1.70% session range. Ether leads the majors at $2,466.63 (+2.04%), followed by SOL at $102.79 (+1.03%) and XRP at $1.3721 (+1.09%). Binance perpetual funding is modestly positive across BTC (+0.010% per 8h, ~+11% annualized) and ETH (+0.008%, ~+8% annualized), while SOL funding sits fractionally negative at -0.0016%. The tilt is consistent with measured long positioning rather than a leveraged chase.

Options Positioning

ETHA prints the day's standout skew. Put-to-call volume of 0.321 against a P/C open interest of 0.645 shows fresh flow leaning heavily to calls, with the $16 strike anchoring both sides of the book (call OI 93,834; put OI 71,976) and 30-day IV at 48.6%. IBIT tells a more balanced story: P/C volume of 0.842 and P/C OI of 0.706, with the $20 put strike carrying an outsized 166,388 contracts in open interest — a legacy downside hedge stack rather than fresh positioning, given spot IBIT at $44.08. FBTC's P/C volume of 0.530 and BSOL's 0.459 round out the call-heavy intraday flow. XRPC remains the thinnest tape at 108 active contracts, with a 0.232 P/C volume ratio that InflowScan data reads as noise given the low base.

Narrative

The tape's dominant story is corporate treasury accumulation. Strategy re-entered the bid with a $370M bitcoin purchase after two months of silence, Strive added 1,800 BTC to become the fifth-largest public bitcoin treasury, and BitMine is closing on its 5%-of-ETH-supply target. BlackRock's BUIDL fund reclaiming the tokenized treasury crown at $2.8B reinforces the institutional-plumbing narrative underneath spot flows. Against that, Metaplanet's disclosed $1B mark-to-market loss on its bitcoin program is the counter-signal on treasury-strategy risk, though it has not visibly weighed on today's tape.

Afternoon Watch

Month-end rebalancing flows into the 4 PM ET close — August marks BTC's strongest month since 2017 on current levels, historically associated with systematic rebalance selling.
USDC market cap down $257M over 24 hours against USDT's +$116M print; a continued divergence would be consistent with prior episodes of US-desk risk-off rotation.
Next Binance perpetual funding print at 16:00 UTC — a jump above +0.02% per 8h on BTC would move the tape out of the current measured-long regime.
