The part of this thread that matters most to me is not whether one large exchange can absorb a loss, but what happens to users while withdrawals are paused. NirvanaWolf raised the custody point well: funds left on an exchange for convenience are still exposed to that exchange's controls, even if leverage trading explains why some traders keep a balance there. A practical split is to keep only what is needed for active trading on an exchange and move longer-term holdings to self-custody, with backups tested before they are needed. That way an incident like this becomes an inconvenience for trading, rather than a question about whether all of your holdings are reachable.
