US crypto-linked index up 0.43% as bitcoin, ether extend gains

The modest index gain against larger spot moves in bitcoin and ether suggests the listed, crypto-linked equity complex is lagging the underlying assets — a familiar pattern when the equity proxy carries its own funding, regulatory and liquidity frictions. Ether's intraday spike and partial retreat points to thinner conviction than the headline percentage implies. Whether the equity index keeps pace with spot, or continues to trade at a discount to it, is the open question worth tracking.
