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
Huge decline on Altcoin market? I don't think it has something to do with the hack.
The decline was cause by smart investors moving their funds to bitcoin. Haven't you check the dominance of bitcoin as of lately? Close to 60% now, which means that the they are all moving to bitcoin ecosystem.
As for the addition of security features, I saw CZ tweets that his people hasn't had that much sleep in the last couple of days, so I'm sure they are working hard on the security as of this moment.
