These are NOT full audits, but they are a start.
These are also not really assets as such, at least not of the exchanges; they are the customer assets in custodial wallets.
The next phase of disclosure is to look at whether any such assets are being used for other purposes, and hence whether funds are truly liquid enough to manage any potentially large withdrawals - the crypto equivalent of a bank-run.
With so many analytic tools employed to discern potential rugpulls and deceptive smart contracts, it really is time to use those tools on the largest blockchain coins.
I suspect we shall also discover rampant insider trading within the exchanges. But that will be another story.
