● The week in review

Weekly Recap — 6 Oct–12 Oct 2026

The week opened with Bitcoin holding firm against a strong dollar and closed with ETF outflows across BTC, ETH, and SOL simultaneously — a first since the products launched. In between, the structural story was the quiet hardening of institutional plumbing: tokenised equities reached mainnet, traditional banks moved into custody, and regulators on both sides of the Atlantic drew new lines. The mood shifted from cautious optimism early in the week to something more sober by Sunday, with geopolitical noise, a Ledger supply-chain breach, and a decade-old XRP inflation bug all arriving together.
