Sep 7 — BTC ETF inflows, Liquid hack, and regulatory shifts

• US bitcoin ETFs pulled in $731M in a single day, the largest inflow since January — renewed institutional demand is providing a strong bid beneath BTC's rally toward $80K. • Liquid Network paused after purported white-hat hackers drained $320M in bitcoin from the sidechain — the incident revives serious questions about federated bridge security and L2 adoption. • Andreessen Horowitz-backed OpenReserve received preliminary OCC approval for a national bank charter built on onchain settlement — a landmark that formally bridges traditional banking and crypto rails.
