With Lightning, you can require a human to approve "pay exactly this invoice", and you set the limits and scope yourself. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin One more thing we love about Nostr: NIP-17 encrypted DMs 📩 npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Using UseBitcoin takes 3 steps. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Has anyone had a bitcoin debit card that just works? Every story I hear goes the same way: the card ships, the top-up works, and then it gets declined at the register. Starting to think the card form factor is the problem, and the fix is converting sats into whatever prepaid system people already use in each country. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin It's got an in-house event coming up, planned by some of us and you're always welcome to join if it sounds fun! :-) npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Oh! Its easy and fun! :-) npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Have you tried agentic payment experience? ⚡ npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Lightning is more capable than most people realize. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin When you want to actually spend bitcoin where you live, what do you do? Merchant maps, gift cards, a prepaid Visa that gets declined half the time? npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin The most fun part of Nostr: zap culture ⚡ npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Allow us to introduce ourselves. UseBitcoin is a Lightning-only online store 🛒 npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin "Bitcoin is for HODLing." We get the sentiment. But money that never gets used never becomes an economy. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin That makes sense! What about using disposable npub/nsec? npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin If you like WoS, you can also try cashu.me and Blockstream wallet. So easy to use and modern UI, depending on how much you wanna stack though :-) npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin We know! Both wallets are simple and smooth right? Lexe is also simple, smooth, and modern, probably its worth a try! npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Nice! Compared to cashu.me, which do you feel is better regarding UX? npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin #UseBitcoin ⚡ npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Which one's your favorite? :-) npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin We're going all in on Nostr ⚡ npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Thanks for the feedback, robdev! npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin "Where can I spend bitcoin in Japan?" We see this question on Nostr every week. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin In Japan, sales received in bitcoin are treated the same as sales received in foreign currency and you just record the JPY value at the time of receipt as revenue. Nothing special needed on the merchant side :-) npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Real-world Bitcoin inbound-payment experiment from Japan 🇯🇵 npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin This one aged well 😌 npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin It's officially live!🚀 npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Finally got it done — we're now NIP-05 verified on Nostr, and our Lightning Address is live! npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Speaking of privacy in Japan, Atsuko Muraki, a Japanese government official, spent 164 days jailed for a fraud she didn't commit — a case built on evidence a prosecutor literally falsified (he altered a floppy disk's timestamp). She was cleared only because a journalist caught the tampering. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Thank you for your inquiry. npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin こんにちは、inkan さん！ npub1dwzecfz4z7fd8z4ks7ye2dcthzvv3rqkwwuhcg78z9m0ffz6he0q5zjj52 JBIinc_bitcoin Thanks for having us!
