wallet or exchage are all vulnerable to hacking. it's just that the more vulnerable is exchage. How can it be? because we know behind the exchage there is a third party. and every hacking shooting event is impossible if no third party contributes. and hackers love a lot of assets. while the wallet is quite safe but can be vulnerable, if there is hacking in the wallet there is an error in the owner. the name man has forgetfulness ... often makes mistakes and negligence in entering an address / password. which causes hacking of the wallet.
