If you think like that way then there is no security for anything or any hardware wallet or any paper wallet or no matter what are you using to protect your asset. Not even a bank can give you 100% security for your asset. Cause bank robbery or bankruptcy is not a unknown thing to us. If you try to use hardware wallet cheaters crack your wallet somehow (like trojan), if you use paper wallet there is a chance to lost it, if you try to use desktop/app wallet they can hack your wallet through email or any other virus.

Those will be happen if we are not much smart to protect your asset. Sometimes for more profit we choose untrustworthy bank, sometime we click a unknown link from our email, sometimes we use unprotected software or application. So there is plenty of way to hack your wallet or PC easily if you are not get smart how to use it.

Honestly i shocked also when i heard about it, cause i also thought hardware wallet is the most secure wallet (which still is). But we can't always judge anything for one or two incidents. Cheaters are everywhere, there is no platform i know about where cheaters are not exist. So being smart is the only way to beat them.
