I asked @bot, and it seems Binance's current net outflows are around $2 billion or less.
Although that may seem like a lot, Binance is enormous. $2 billion accounts for only 1.5% of total user assets.

By comparison, when another exchange was hacked in September, during the first hour of withdrawals being opened at $BTC , 4,000 $BTC ($300 million) was withdrawn—more than 5.5% of total user assets.
It seems most users still have a lot of faith in Binance?
