Crypto exchange Coinbase appears to be having trouble keeping its platform up and running amid the heightened bitcoin trading activity over the last few weeks.

Some Coinbase users reported seeing zero balances in their accounts as the price of bitcoin rallied past the $68,000 mark. 

“We are aware some users may experience increased latency across and a few users may see intermittent zero balance. Rest assured, your funds are safe,” said the Coinbase team in an X post. 

This is the second time in two weeks that users have reported a similar issue with their Coinbase account balances, and glitches during buying and selling cryptocurrencies on the platform. Last week, the exchange’s CEO Brian Armstrong attributed the problem to a “large surge of traffic.”

While the Coinbase outage sparked panic in some users, others were relatively unfazed, calling an exchange overload a typical indicator of a crypto bull market. 

At the time of writing, bitcoin was trading at $68,600, gaining 8% over the last 24 hours. Data from CoinMarketCap shows that trading activity for the leading digital had seen a 117% jump over the same period, with volumes across exchanges topping $68 billion. 

On Monday, bitcoin hit an all-time high against major currencies like the euro and the British pound, as its market cap hit a record $1.3 trillion for the first time.
