Show HN: Create Custom Bitcoin Banknotes with Your Own Portrait (github.com)

We built HongbaoBTC, a web app that lets you design and print Bitcoin paper wallets styled like traditional banknotes — but with a twist: you can add your own face (or someone else's) in the portrait area.

It’s a fun way to make crypto gifting more personal and tangible. Inspired by cultural traditions like hongbao (red envelopes for gifting money), HongbaoBTC lets you gift Bitcoin with a personal touch — perfect for birthdays, Lunar New Year, or any special occasion.
