BTC Down Over 10% While ETH Holds — VanEck’s Sigel Calls First‑Since‑2021 Bearish Signal with Historic Median 15.6% 30‑Day BTC Drop

COINOTAG News reported on August 27 that, according to VanEck analyst Matthew Sigel, BTC has registered a cumulative decline of over 10% while ETH has not—an occurrence flagged as the first time since 2021. The analyst noted this market configuration has appeared only 52 times since 2020, highlighting an uncommon divergence between Bitcoin and Ethereum price action.

Drawing on historical outcomes, Sigel cited median short‑term moves: BTC -2.8% (7 days), BTC -15.6% (30 days), ETH +6.4% (7 days), and ETH -8.4% (30 days). He characterized the pattern as a bearish signal for the broader cryptocurrency market, with ETH providing transient support even as both assets signal potential trend reversal, per the reported data.
