Binance has been considered one of the safest exchange out there. If hackers can penetrate with all the security measures then it proves that much more needs to be done to secure investors funds.
After this attack, Binance definitely needs to add other security features to make everyone's withdrawal safe. This will happen the week after Binance has official announcements on this issue. In the meantime, consider investing in altcoin which is present in this exchange because the loss of 2% of the BTC has caused this market to have a huge decline. Anyway Binance still guarantees assets for customers so I won't worry much about this
