Are Hardware Wallets fully Safe and impossible to hack even by the creator?!
Many people trusts in hardware wallets but what will happen if the creator is an evil?! .
I think he/they can easily stolen bitcoins!
I'm not sure about that but i was learning from someone that bought second-hand nano ledger and then the first user of that nano ledger is exploiting the wallet and then the buyer lost a lot of money.
But trezor is having a better security rather than nano ledger and you must buy it.
