Wild contrast this week — a so-called white hat lifted 4000 BTC off the Liquid sidechain, a reminder that "friendly" hacks still mean funds moved without permission. Meanwhile Bitcoin ETFs just logged their best inflow stretch of 2026. One story shows lingering infrastructure risk, the other shows institutional appetite isn't slowing down. Worth watching if Liquid addresses the breach transparently, and whether ETF demand keeps absorbing any nervousness from it.
