[Edit: Oh, .. I see ... to cause a delay of a selloff.]
If I send a deposit transaction to an exchange and the fee wasn't high enough, and I didn't have RBF set, and I don't know about CPFP (or can't use it because it came from a custodial wallet), then my deposit transaction doesn't confirm and I won't be able to sell.
I think its to discourage withdraws rather than to delay a selloff

So this delay in withdrawals would prevent a bank run right? My thinking: if there are too many withdrawals and Binance had fractional reserves at some point they'd have to pause withdrawals, which would result in widespread panic
