Coinbase Denies Hack Claims as Loss Reports Grow
Coinbase faces allegations that it concealed repeated hacks after customers reported major account and fund losses. BlockTower Capital founder Ari Paul claims Coinbase lost $25 million belonging to his firm and that more than a dozen companies suffered over $1 billion in combined losses. He has not released public evidence, citing ongoing legal proceedings. Coinbase denies hiding hacks or losing $1 billion and says it cannot comment on specific customers. It has advised users to secure their API keys. The dispute began when trader Kuno accused Coinbase of holding $1.2 million after more than 30 unresolved support tickets. Coinbase executive Jordan “Cobie” Fish questioned the claim’s authenticity and said recent outreach received no response. Former Coinbase employee Justin Mart suggested stolen credentials, potentially linked to the Lazarus Group, could explain BlockTower’s losses. Paul rejected that explanation and said forensic firms and US investigators were involved, offering to publish evidence if Coinbase agreed not to sue or harass him. Coinbase separately disclosed in May 2025 that criminals bribed overseas support agents to steal customer data and rejected a $20 million ransom demand. Paul has not linked his allegations to that breach. The claims remain unverified, but the Coinbase controversy could increase scrutiny of exchange security, customer support and API-key controls.
Neutral
The allegations are serious but remain unverified, and Coinbase has denied concealing hacks or losing $1 billion. In the short term, renewed reports of customer losses could weaken confidence in exchange custody and trigger caution among traders, but they do not directly indicate selling pressure on any specific cryptocurrency. The documented 2025 data breach may reinforce concerns about customer support and API-key security, yet Paul has not linked it to his claims. Unless credible evidence emerges, the direct price impact on cryptocurrencies is likely to remain limited. Confirmation of widespread losses could create broader risk aversion, while a clear rebuttal or independent findings could reduce the pressure.
