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 ?
Even if it is safe, why risk it? Would you risk putting your money into other person bank account? Of course not, if you cannot afford a hardware wallet then wait until you can, it is a waste of money to buy a hardware wallet and store there a small amount of bitcoin.
