If there’s a massive company or venture capital involved, sure, but nostr.com doesn’t really justify what cars.com was valued at $872 million a decade ago. That company earns almost $700 million a year. What’s the potential ROI on a website that doesn’t sell anything?

It could sell relay services and nip5s to start.

Okay, for the sake of argument, the nostr.wine relay costs 18888 sats, or around $5 flat-fee. You'd need to sell a million subscriptions just to break even on the cost of the domain name before factoring in operating costs. That's a tall order for a protocol that currently has maybe 10,000 active users. It's great to have big dreams, though. Maybe someone will figure out a viable business plan, but I echo what @semisol and others have said that the name should not be owned by a company operated for profit because of the risks of becoming co-opted and centralized.

Tout dépend du secteur surtout en Europe
