I don't have a technical design in mind .. my point is most people have only one device .. this device is smartphone .. for example camera , music player , scanner - and so many other gadgets already merged into one ..

So instead of offering people more choices , might as well build one that has at its core a Bitcoin wallet ..

presumably one can use Bitcoin npub as a #nostr npub too .. add a private relay on top and you have a working plumbing for one device that carries your value and your influence..
