Do you get irritated whenever someone close to you buys a bunch of shit they don't need?
Are you immediately converting the amount of fiat they spent to precious sats which they would've gotten?
Now you have a chance to shame them!
Simply head on to print the PDF files linked in the Let's shame someone! section and let your friends know that you've noticed their behavior. Perhaps one day, they'll understand the importance of saving in bitcoin!
Anyhow, these cards are 3.5 inch by 2 inch (business card size), so you can make someone feel bad, while being professional about it.
Feel free to modify these cards and make your own translations :)
Also I'll be moving the project code from gitlab to github and making it open source so anyone can fork it and make their own version :)
