Hey guys,
I have some BTC on my Ledger Nano S and I want to link them for the Airdrop of Stellar Lumen.
However when I try to sign the message I get this response:
"Failed to Sign Message: Invalid index offset"
I have researched a bit and it seems to be an issue with Ledger Nano S right now.
Is there a reliable OFFLINE tool, which I can download, to sign messages from Bitcoin in general since I have the private keys, but don't want to insert my details into a website form?

Best regards

Hey guys, does anyone know a wallet where I can create multiple BTC adresses and also label and name them? I get several passive payments and want to sort them out for comparison reasons. And have each of them come to a named Bitcoin address from me and compare them.
Is there such a wallet on the market right now, or how do you keep track of all the different addresses?

Hey guys,
I want to convert some BTC to dollars in PayPal Balance so I can buy something else, since the shop doesn't offer crypto support.
Do you know a service which can transfer BTC to paypal credit, so I don't have to trade it manually back to fiat and then get it on my bank account again?
Best regards

Hey guys,
I was just wondering that if I were to lose my phone now that I have linked all the Bitcoin exchanges to it with the Google authenticator app, would I lose the access?
Is there a way to "backup" the safety feature like Google Authneticator?
Many thanks in advance!
