Bitcoin Price Prediction for October 2026: 10Y at 5.19% Tests $81.3k Support as ETF Inflows Stall
Bitcoin's 44% three-month advance is now colliding with a 5.19% 10-year Treasury yield and a 79,306-transaction mempool backlog, exposing the rally's dependence on reflexive ETF flows rather than organic on-chain demand. With the 10Y-3M spread at +1.11% and the Fed pinned at 5.33% effective, the marginal dollar is rotating from beta into front-end carry — and BTC is the first casualty.
