Bitcoin declined 0.3% to approximately $83,700 on Wednesday as markets positioned ahead of the personal consumption expenditures (PCE) price index release.

CryptoQuant data indicates weakening demand dynamics, estimating spot Bitcoin demand has contracted by roughly 170,000 BTC over the past 30 days while futures demand growth has plummeted 90% since September 14. Ether fell 0.7% to $2,690, with HYPE dropping nearly 2% among major tokens, though XRP and TRX posted marginal gains under 1%. Broader macro conditions remain tense as Brent crude climbed above $103 per barrel, up 14% in September, and 30-year Treasury yields touched their highest level since 2002 before stabilizing.
