It's normal to have a trust issue towards Binance since they are lacking a security from hackers. However, I will still use Binance since none of users get their wallet hacked as of now. Those BTC7k was from Binance funds, not from users' funds. On the other hand, it's better to just wait for the result of their investigation and don't submit any KYC requirement as it's still necessary to trade there without requiring to be a KYC approved.
The fund was actually from user’s fund, just that it was targeted at some account, maybe those accounts that has those bugs that could make them crack the wallet through Binance, that is why they made refund of the $41 million, if it was from their own personal account, they would not have had to refund anything again, but let’s keep that aside, that was just a onetime mistake.
I am sure that they have put everything in control, and when this issue of second hacking of data came, I really doubt the truthfulness of the news, and I dint think that they will be that loosed again to allow a loophole in their data system, except maybe they never imagine that someone could be interested in the data, and if that case was real, then some people may have deliberately done that.
