a far cry from zero, and the CZ tweets triggered a run. How many other exchanges have enough assets on hand to cover every depositor at once instantaneously? Even mainstream banks cannot cover everyone (this is what a bank run is and is why central banks exist to provide a backstop in such an event).
Straw man. You said SBF "was technically not lying about FTX having the money." He was. If you ask me to hang on to your $12 and I spend half of it, I don't have the money.

All of them. Exchanges and clearinghouses in a proper financial system are fully collateralised.

Banks are leveraged. FTX was not supposed to be levered. It should have been able to survive a "run," because it wasn't supposed to have asset-liability mismatches.
> there are 200+ exchanges. you're saying all of them are fully collateralized?
In crypto? No. Because it's a marketing term there for brokers. FTX was, at the end of the day, a broker. (As is Coinbase and the other "exchanges" for how most people use them.)
In finance? Yes. Most exchanges (all in the U.S.) don't handle settlement; that's done by a clearinghouse, where the counterparty risk lives. They're fully collateralised [1].
