To the best of my understanding,
- starting state had FTX as insolvent, but had enough money to cover the withdrawals of their token (FTT)
- Binance CEO announces that they're going to dump all of their FTT because they don't trust the stability of it
- now there's a bank run, and people are making enough withdrawals to expose that FTX is insolvent
- FTX pauses withdrawals (because they don't have the cash)
- Binance bails out FTX by purchasing it
