Regular markets have circuit breakers [1] that stop trading for a period of time. Coinbase should just define and implement these to let their systems catch up.
Coinbase is unintentionally the circuitbreaker. It crashes every time there is a lot of volatility.
That is insane. Traders make money during periods of high volatility and volume. Defined circuit breakers can be planned for, but unpredictable "lol unavailable gtfo" is unacceptable for serious usage.
