Hello my friends.
Is that safe to buy a used hardware wallet like Ledger Nano S or Trezor .
Is there any danger to use a second hand hardware wallet ?
Hello there my friend. The first question will be, will you be storing a huge amount of bitcoin? If yes, I would say you do not compromise them. Why don't you buy a brand new one? The reason why you buy them in the first place is that you want to safe-keep them right? Well the safer way to do it is not to safe-keep them in a hardware wallet that is already used.
