Coinbase, the largest cryptocurrency exchange in the U.S., experienced widespread outages, with multiple reports of users seeing zero balances in their accounts for the second time in less than a week. The issue, attributed to high traffic on the website amid a Bitcoin rally that hit $67,000, was described as a glitch in the system. Coinbase assured users that their assets were safe and that only a small subset of users might see intermittent zero balances and experience latency across pages. Despite the glitches, trading was not impacted at this time.
