I asked @bot, and it seems Binance's net outflow is currently around 2 billion. While it seems like a lot, Binance is a massive company. 2 billion only represents 1.5% of total user assets. In contrast, another exchange was hacked in September, and within the first hour of reopening BTC withdrawals, 4,000 BTC (300 million USD) were withdrawn, representing over 5.5% of total user assets. It seems the vast majority of users still have a very strong sense of trust in Binance?
