Print on demand for sats doesn't exist to my knowledge, so for physical copies you have these options: Partner with American and European distributors and send them a print run for fulfilment. Sell in person at meetups and conferences. Sell via your website (e.g. BTC pay or just a Lightning address and form), then and personally mail the book. The issue is that customers (even bitcoiners) are used to fake shipping costs. Amazon makes a loss shipping books for free. When confronted with a $10 shipping cost for a book, bitcoiners just run back to Amazon.
