Coinbase detailed its cold-storage controls after reporting that more than 99% of customer assets remain offline and that it was unaffected by the Binance breach.
Coinbase detailed its cold-storage controls after reporting that more than 99% of customer assets remain offline and that it was unaffected by the Binance breach. This is an original Token Times brief synthesising 2 outlets (Cointribune, Decrypt), with their figures cross-checked, plus live market data, as of Thu, 05 Nov 2026 17:00:01 UTC.
Coinbase’s storage setup illustrates how exchanges limit the amount of customer assets potentially exposed to online compromise. The size of the reported online balance makes the control relevant amid heightened concern following the breach at Binance.
- Coinbase reports over 99% of customer assets are held in offline cold storage.
- Cointribune puts the remaining online balance at $3.8 billion.
- Coinbase says it was not affected by the reported Binance breach.
- Bitcoin fell 5.45% over 24 hours as the broader market declined.
Cointribune and Decrypt agree that Coinbase reports more than 99% of customer assets are held in offline cold storage. Cointribune quantifies the reported online portion as 1%, worth $3.8 billion, while Decrypt highlights split private keys and kill switches as additional controls and says Coinbase was not affected by the Binance hack. The outlets describe the Binance breach as $6.34 billion and $6.4 billion, respectively, while neither contradicts the other on Coinbase’s storage ratio or security model.
Coinbase told customers that more than 99% of customer assets are held in offline cold storage, according to Cointribune and Decrypt. Cointribune reported the disclosure on November 4, days after a breach affecting Binance. Decrypt also reported that Coinbase said it was not affected by the incident.
The most detailed figure comes from Cointribune, which said approximately 1% of customer assets remain online and valued that portion at $3.8 billion. That online fraction is not merely a residual share: Cointribune’s figures make it a material balance within Coinbase’s customer-asset storage system.
Decrypt outlined several controls beyond cold storage. Coinbase said it uses split private keys, meaning key components are separated, and kill switches that can disable systems. These details were specific to Decrypt’s coverage, while both outlets independently corroborated the over-99% offline-storage figure.
The disclosure came against the backdrop of the reported Binance breach, which Cointribune placed at $6.34 billion and Decrypt described as $6.4 billion. The differing descriptions amount to rounding rather than a substantive disagreement. Coinbase’s claim that it was unaffected was carried by Decrypt, and the company’s own statement made the storage statistics self-reported rather than an independent audit.
Live market conditions were broadly negative: total crypto market capitalization stood at $2.62 trillion, 
Bitcoin was down 5.45% over 24 hours, and the overall market was broadly lower. The Fear & Greed Index stood at 50, labeled Neutral. The Coinbase disclosure arrives amid those declines and renewed attention to how exchanges protect customer holdings, with the reported $3.8 billion online balance, the Binance breach figure, Coinbase’s security controls, and subsequent disclosures the principal items to monitor.
