What's the problem in this case
The real issue is that people are using a wallet of the exchange platform and don't have their private keys to confirm ownership. In this case, it's all up to Binance to take care of your crypto assets security. In this case, it was not a successful achievement.

Even with many security layers like 2FA, password, transfer confirmation by email, and other security features, it was not possible to stop the hackers to take 7K BTC.
It's not just a problem for Binance owners, the whole crypto community is suffering from such issues.
In the meantime, the Bitcoin price is rising more and more.
