It could be just that they were serious but the scope and size of the problems were so obvious that it became clear in just a few hours that it would be criminal insanity to rescue the scammers at FTX - from what I've seen they were using customer funds for their own uses.  I don't know who was buying what FTX was selling for so long - to me, it just seemed like they were incompetent and dodgy from the start.

Like celsius, they just seemed like corrupt from the start.
