Hi guys, my question may be very silly, but i really need to know

I want to ask if i instal some wallet on pendrive send there some f.e. BTC will i get very cheap hardware wallet ?

Did anybody try that ?
If you attach that pendrive to some random PC that is infected, it will steal your bitcoins (if not encrypted). If encrypted it will wait to you provide password to send bitcoins and then steal it.
Hardware wallets have additional layer of security out there

this is main difference from pendrive.
