I really do my best not to be pedantic but I think it’s important enough to make the distinction that #Bitcoin is not “in” hardware wallets. 

Hardware wallets are signers that hold keys securely. Bitcoin balances only exist within the Network’s immutable distributed ledger. An individual owns Bitcoin when they securely hold keys and the signing device that allows for control of those funds within the Bitcoin Network.

I’m sure you know this but newbs to Bitcoin and/or #Nostr may not. It’s critical people understand these nuances so they can properly interface with Bitcoin. 

Rest of the post is spot on.
