According to @cas_abbe, Bitcoin ETFs purchased $322.8 million worth of BTC yesterday (source: @cas_abbe on X, Sept 3, 2025). Ethereum ETFs simultaneously recorded $135 million in ETH net sales (source: @cas_abbe on X, Sept 3, 2025). @cas_abbe added that strength in gold could be driving renewed interest in BTC (source: @cas_abbe on X, Sept 3, 2025). For traders, these ETF flow differentials point to institutional rotation toward BTC over ETH and warrant close monitoring of BTC dominance and the BTC/ETH pair for relative momentum (source: @cas_abbe on X, Sept 3, 2025).
