This is an absolute joke, and utterly unacceptable. There is no "I'm fairly sure" or "to the best of my knowledge" here. You either knew or you didn't. Even if you actually didn't know, which I don't believe for a second, monumental negligence should not absolve accountability.
Expanding on DealBook:
When I filed, I'm fairly sure FTX US was solvent, and that all US customers could be made whole.
To my knowledge, it still is today.
I was expecting that to happen. I'm surprised it hasn't. I'm not sure why US withdrawals were turned off.
