On March 4, some users of the crypto exchange Coinbase experienced an issue where their account balances appeared as zero. At 5:36 pm UTC, Coinbase acknowledged the problem, stating that a small number of users might see intermittent zero balances and slow page loading times, but trading was unaffected and users' assets were secure. The company implemented a fix by 6:21 pm UTC and continued to monitor the situation, declaring it fully resolved by 8:29 pm UTC.

A similar incident occurred on February 28, when users also saw zero balances and were unable to trade. This issue took about seven hours to resolve. Although Coinbase has not confirmed the cause of the latest issue, it suggested that increased traffic was a factor in the February 28 incident. Coinbase's trading volume surged to $7.5 billion in 24 hours, a 120% increase, likely due to Bitcoin's price reaching $67,481, close to its all-time high.

The problem is likely related to sudden surges in traffic during the market rally, despite speculation about other possible causes.
