Bitcoin was quoted at $85,066.5 on Sunday, October 4, up $446.3, or 0.53%, on the Investing.com board. The same tape put the session between $84,718.8 and $85,194.5. That is a $475.7 high-to-low span, narrower than Friday’s swing through the mid-$86,000s.
Saturday’s reference on a MyTrade Academy board was $84,591, with that day’s range listed at $84,254 to $86,813. The Sunday print sits about $475 above Saturday’s mark and about $1,750 under Friday’s high. An OKX daily table showed October 3 opening at $85,330.10 and closing at $84,864.30, with volume of $352.38 million.
Spot bitcoin ETFs do not file a Sunday flow. The last completed weekday on the BingX recap of Farside figures was October 2: $102.7 million of net intake, led by BlackRock’s IBIT at $195.6 million against a $60.7 million redemption in Fidelity’s FBTC. A later WhaleRoom snapshot labeled the same calendar day at $31.7 million. The two desks are not using the same cut. Neither number is a Sunday print.

Why is Bitcoin’s October 4 range only $476?
The Sunday board did not retest Friday’s high. From $84,718.8 to $85,194.5 is less than 0.6% of the price. That is a holding pattern, not a new range break. Polymarket’s October 4 contract for a close between $84,000 and $86,000 was last marked at 94.5%, with the “above $84,000” contract at 97%, both due the same day. Those are contract prices, not a forecast from this desk.
Thirty-day performance on a MyTrade series dated October 4 was still positive, near 5%. The one-year line on that board was down about 31% from the October 2025 peak area above $126,000.
What to watch next
Monday’s ETF file. If IBIT’s October 2 bid does not return, Sunday’s $85,066 print is a weekend mark, not a new base. The level that still matters from Friday is $86,813.
