My aunt's daughter Died and there is 13 btc in hardware wallet she left 2 kids and we my family know nothing about btc or this field i help her to buy this coins. I have her laptop she use to open the wallet from and we have the bill that we buy Ledger Nano. So what we can do to solve this mess?
What do you need your post is confusing. You should watch some
YT for tutorial on how to use it so you wouldn't get confused and wouldn't lose the Bitcoin. You should just know her pin to access the ledger or since you have the bill try finding the paper where she wrote the pass phrase. And please don't do anything stupid like posting it on social media because the wallet could be hacked and you wouldn't use anything from it.
In my guess, this is easier to solve because some information must be there somewhere. They just need some guide on what to look and how to use the information they can find. And yes, watching some YouTube can help. I advise them never to trust anybody outside as we don't know if one can be tempted to do something unfortunate. I am wondering if Ledger Nano has a hotlink or customer support for a matter like this, anyone?
