The only way I'd use nostr:npub1mftv2j67vayavkks8rqev3u8jjhefe86tf80msstfxvpunk9vmps6prkl3 (p2p like LocalBitcoins, but with a marketplace as well) is by using one of these services. I guess nostr:npub1l0mkfdgycmcy6as3ypmlpm7xwwk27cul3gmzg525kgsrwq57dvusksx3xd is the way to go.. nostr:npub1mftv2j67vayavkks8rqev3u8jjhefe86tf80msstfxvpunk9vmps6prkl3 requires a cell phone number to get an account.
