Has there ever been a case where a user's bitcoin had been stolen by way of simply connecting the hardware wallet to the computer?
(....)
Phishing websites or software / malwares installed on computer. There are few issue before on Ledger regarding of email on the user of ledger hardware wallet where the email consist of phishing site and asking user for the hardware wallet's seeds.
Storing hardware wallet's seeds online may not be safe and good move.
What I love using hardware wallet is there is no way to get your funds as long as nobody knows your seeds or keys.
