The hackers drained the exchange’s hot wallets, taking 7,000 bitcoin, worth approximately $41 million, in a single transaction. The hack only amounted to 2% of the exchange’s total holdings. Everything else was in its offline cold wallets.
The exchange will use its Secure Asset Fund for Users (SAFU) to cover the losses. In mid-2018, after an earlier hack, Binance began to allocate 10% of all trading fees received into the fund, as a way to insure against extreme losses.
When you read that don’t forget how other exchanges have dealt with such problems.
Edit:
Some people are asking if Binance could still do that with today’s prices. Here are Binance’s SAFU wallets:
16,277 BTC – $431,226,563

100,000,000 TUSD

That is a total safety fund of $927 million.
