This isn’t just a shirt—it’s a cipher in cotton. The Twenty One OPSEC Bitcoin T-Shirt hides 21 in plain sight, with the number 2 inserted in the “n” in “twenty” and the 1 stealthily carved into the “n” of “one.” It’s a design only true believers will decode, nodding to Bitcoin’s 21 million hard cap without uttering a word. Perfect for those who live by self-custody, privacy, and proof-of-work principles, this tee is a quiet anthem for the orange-pilled. Clean, clever, and conspiratorially cool, the Twenty One OPSEC Bitcoin T-Shirt turns minimalist streetwear into a statement of intent.
