First 2023 design addition to our Proof of Work Apparel (TM) line of products for Bitcoiners.

Up your game, print your apparel with sweat activated ink. Graphics printed using sweat activated ink are completely invisible until activated with moisture. As the shirt becomes wet, the design begins to appear. The more the person sweats, the clearer these graphics become. Once the shirt begins to dry the images disappear, ready to start the cycle again. Are you ready to put in the work?

Made in America.

"The best Bitcoin game I've played! It's a fun game on its own, but the Bitcoin parallels make it an excellent teaching tool too!"

"HODL UP is a fun game. Almost as easy as playing Uno. Cool thing is that... it is all based on crypto-currency. Playing enabled my children and me to learn as we mined coins! Its accessible gameplay makes it both a family-friendly game and an educational experience. Highly recommend!"

"I was so excited to learn that Scott and his family created a Bitcoin-themed board game. I played it once and I was hooked: I had to buy a copy of my own (using the Lightning network, of course). This game brings into focus many of the key concepts and features of the Bitcoin network and prompts important questions and discussions with folks who have not yet been orange-pilled. Meanwhile, we are all playing a well-balanced and fun board game!"
