Proof of Keys Bitcoin Shirt
Every year on January 3rd, Bitcoiners celebrate the annual Proof of Keys event which was created to encourage individuals and businesses to take control of their Bitcoin keys and to not keep them on third party custodian platforms such as exchanges. The Proof of Keys event takes after the manta, not your keys not your coins. The unisex heavy cotton tee has specially spun fibers that provide a smooth surface for premium quality and sharpness. No side seams mean there are no itchy interruptions under the arms. This shirt is available in various colors.
