Im considering buying hardware wallet from ledger as I want to control and own my funds instead of having everything on exchanges.
My question is what will happen if ledger site goes offline completely and the owner disappears, ...
I think you can still use it even though the Ledger website is closed because you control the private key of your hardware wallet.
... will the wallet still function? even in 1000 years? ...
Humans cannot know how long the Ledger is functioning, but at least the hardware wallet has more resilience compared to other wallet types.
...
Do you guys think ledger is a good choice? are they trustworthy etc?
are there any risks of the hardware wallets being bugged so they can steal funds later from all users?
