Who have it for free? That's usually a big red flag.
Ledger recovery wants you to broadcast your seed words to them. A lot has been written in another topic, long story short: don't do it. Ledger is not cold storage.
Not a red flag at all. I got it from my brother, who recently passed away. He was going to use it on his account. Since he didn't use it, I will use it.
It was NOT offered to me by any company. Just my brother's personal posession, that he never got around to using.
About the subscription. That seemed to me to defeat the purpose of having the hardware device. But are you saying that the nano 3 (itself) is not a cold wallet? or only not so, if you get the recovery subscription?
I'm going to try and cancel that subscription, if it's not needed.
