Was thinking about that some months agoo
at the end wallet of satoshi works by email, (of course you are not trusting with a lot of money) but it's only a simple email not the whole cloud stores thing..
nostr key are very simple to generate and store 🤔 actually making it super interesting as a first impact for someone new !
I mean the first impression of " I am the one owning what i post here" will go disappearing ( for that kind of users).
Nostr could grow by some clients using this ( that will also lock user in THAT client, since property log in connection).
But it will not spread the nostr protocol meaning.
New user simply won't get what is this about and will be set apart.
I'm late at work for writing this 🙃 🤣
