The hackers seems to have developed more sophisticated means of carrying out their heinous acts. They kept on trying to break the security protection of the registered accounts. Just be careful with your account that's all.
I think black hat hackers are really smart, which is why white hat hackers must know how black people think. It is their duty to protect exchanges because hacking will make exchanges less credible and will affect the entire crypto market. Just like what you say, investors start to fear now.
One reason why the market is currently downtrend. Exchange security is so low that they cannot protect it from hackers and intruders. The technology they use for security is not guaranteed and is strong enough to withstand hacking.
