Bitcoin Halloween Shirts.
Four black tees for October 31, from a pumpkin pun to the Halloween email that introduced the Bitcoin white paper.
Looking for a Bitcoin Halloween shirt that a bitcoiner will actually laugh at? Our four Halloween tees are black unisex crew necks, each with one orange line-art object and bold white words that read well across a crowded room, so the joke lands before anyone asks what it means. Three are Halloween puns, and one is a straight history piece built on a real date: the Bitcoin white paper was emailed to a cryptography mailing list on Halloween 2008. Pick the design that suits your friend, then order early, because every shirt is printed after you order it.

Choose the right Halloween joke
- The pun for a rules fan. No Tricks, Just Math sets an orange candy corn above NO TRICKS. and JUST MATH. It turns trick or treat into a claim anyone can check, since Bitcoin's rules are published and anyone running a node can verify them.
- The easiest pun to explain. Trick or Sats shows an uncarved orange pumpkin with no face, over TRICK OR SATS. A sat is one hundred millionth of a bitcoin, and our sats guide explains the rest, so the joke lands even with a friend who has never heard the word.
- The history joke. The Best Treat of Halloween 2008 is a round candy pail with a wire handle. The shirt's opinion is that the best treat of that year arrived by email, on Friday, October 31, 2008.
- The literal history piece. Bitcoin P2P E-Cash Paper, Oct 31 2008 draws a curbside mailbox with its flag up, and the lettering echoes that email's subject line. It is the most literal of the four, and our white paper explained guide covers the paper itself.
Order early for October 31
Looking for costume and party ideas as well? Our bitcoin Halloween ideas guide has easy no-prop costumes, candy puns and a party game.
Halloween falls on Saturday, October 31, 2026, and every shirt is printed to order before it ships. Our published times are 3 to 4 business days to print, then about 5 days to arrive in the continental US after shipping. Alaska, Hawaii, Puerto Rico and other territories can take about two weeks after shipping, so they need the most room. These are typical times, not promises, so the sooner you order, the safer the gift. We ship to US addresses only, and two tees at $39.99 each clear the $75 line for free US shipping.
Questions
Good to know
Can I still get a Halloween shirt by October 31?
We cannot promise a date. Printing takes 3 to 4 business days and delivery in the continental US about 5 days after shipping, so an order placed this week has the most room. Later orders may still arrive in time, but the risk grows, fastest for Alaska, Hawaii and the territories.
Can I change or cancel a Halloween order?
Yes, until production starts, which usually happens within 24 to 48 hours of ordering. If you need a change, email support@bitcoincasual.com as soon as you know, rather than waiting.
What sizes do the Halloween tees come in?
Every design comes in XS, S, M, L, XL, 2XL and 3XL at the same price of $39.99. If the size is wrong, an unworn, unwashed tee can be swapped for another size within 30 days of delivery, and the customer pays the shipping. The returns and exchanges page has the details.
What if a Halloween shirt arrives misprinted?
A flawed, misprinted or wrong item gets a free replacement if you report it within 30 days of delivery and include a photo. Email the photo to support@bitcoincasual.com with your order number.
