Clarification: depositors are considered a banks senior creditors. They get paid before the other creditors.
The reason a bank would suspend withdrawals is so it can be either taken over in an orderly fashion (in the US supervised by the FDIC) or so they can get a liquidity infusion (in the US, depending on their charter, from the fed).
Those regulatory agencies and bankruptcy rules don’t exist for a crypto exchange so there is very little an exchange can be doing when suspending withdrawals that doesn’t end with the exchange going bust.
