TechFlame reports: According to official sources, Coinbase has announced that spot trading and advanced trading features on its platform have been temporarily suspended as part of a planned maintenance operation. The maintenance is expected to last up to 4 hours. Coinbase will provide an update once trading resumes. Currently, order books for all trading pairs have entered "cancel-only" mode, which will persist for approximately 10 minutes before Coinbase proceeds to disable all remaining platform functions.
