Okay, we have to admit something.. We’ve had an Advent calendar going on since 1st of December, highlighting our favorite Norwegian Bitcoin merchants and companies. But guilty as we feel, it has only been published on X.. That has to change, so today’s door will be broadcasted as a note, transmitted by relays first, and then as a tweet on X a little bit later on. We will also publish a summary of the other doors we’ve previously opened on X, because we think many of you lo find value in them, even if you’re not Norwegian. Let’s go! 🧡
