"Where can I spend bitcoin in Japan?" We see this question on Nostr every week.

Honest answer: you don't need to find a shop that accepts BTC. You can turn bitcoins into Japanese gift codes (au PAY, DMM, BitCash, QUO…) in about a minute.

No account, no KYC, no bank. Just a Lightning invoice. That's what we built usebitcoin.jp for.

Starting today we're running an experiment. Buy anything, DM us your order ID and what you used it for, and we'll zap 2% back in bitcoins.
Payouts go out in a batch, roughly one month after we receive your DM.

Every DM gets read by a human and your use case can decide what we build next.🚀🚀🚀

⚠️ DM only, please and use **private DMs (NIP-17)**; Damus, Amethyst, 0xchat all support them. Legacy DMs (NIP-04) leak who-messaged-whom and are easier to attack, so we can't read or reply to those. And don't put your order ID in a public zap comment — everything on Nostr is public, including zap notes.

Looks like none of your profile info is loading/displaying on Amythest, also DM relays aren't set so can't DM you

This is a problem I was facing recently, i.e. asking other Nostr users to get in touch with me privately. I hadn't used DMs myself and, looking at what's available, I still don't really feel comfortable to invite users with whom I don't have a previous relationship to first make private contact wit...
