The dollar amount on each city is the estimated living cost for an individual to live comfortably in that city for a month. If you're not traveling to that city, then you don't need to worry about it.

If you sign in on a desktop, you can use a browser extension like keys.band to sign into Satlantis with your current Nostr account. We should talk over the phone soon, so I can help you with that.

If you create a new account on Satlantis (which you can do on mobile or desktop), it will create a new Nostr account that won't be linked to your current one (don't feel dumb if you did that; *I* did that when Satlantis was first being developed, and I *work* there! 😅).
