I Love Bitcoin T-Shirt

No meme to decode, no slang to explain: just three words. This tee is for anyone who is happy to say how they feel about bitcoin, out loud and in public.

Couples around the world fasten padlocks to bridges and railings as a sign of lasting love, often tossing the key into the water below. The custom grew so popular in Paris that part of a railing on the Pont des Arts gave way under the weight in 2014, and the city removed the locks the following year. A heart-shaped padlock suits bitcoin neatly: devotion on one side, and on the other, security that depends entirely on who holds the key.

An easy gift when you are not sure which bitcoin joke someone likes, since everybody gets this one. It is bright and friendly, so it suits Valentine's Day, birthdays, meetups and ordinary weekends. Couples who both hold bitcoin could make it a matching pair.
