Can Ledger company keep private keys for the public keys generated by the Ledger Wallet to steal my money?
E.g. they create bitcoin public and private keys, save it. My wallet "generates" these keys, I put money there, they take my money as they know the keys.
They'd have to keep an awful lot of private keys to be able to do this...
You can continually reset the device as many times as you like, generating a new randomly generated seed (and thus, new private and public keys) every time you reset it...
It's not a problem to keep thousands keys for every device.
In my imaginary situation device doesn't generate random public and private key. It gives the next pair which Ledger company knows
