I think CZ got away with a very modest sentence (if that's the total sentence, based on all charges), good for him. That makes it seem that the crime wasn't a big deal, which can also be good for the reputation of Binance.
But CZ being in prison doesn't mean that Binance will stop working (especially when we're talking about the global exchange) or that people wouldn't be able to use the funds they have there. I'm all for self-custody and I don't keep funds on exchanges, but I'm just pointing out that this particular news on CZ probably doesn't affect the money on the exchange.
