Binance reopens 87 networks after $6.3 billion breach as BTC flows draw scrutiny
Binance has reopened withdrawals across 87 blockchain networks as it recovers from a $6.3 billion security breach on Oct. 29, 2026. Market data on Binance's bitcoin reserves, inflows, outflows and netflows suggests an unusual pattern during the recovery. A breach of this size at the largest exchange is a major confidence and liquidity event for traders watching BTC flows and counterparty risk.
