I designed this cap as a tribute to the beautiful, predictable, and unchangeable monetary policy of Bitcoin. My "Halving Block Heights" Trucker Cap is a piece of pure OPSEC for the true student of the protocol. It features a simple, vertical list of the first four halving block numbers (210k, 420k, 630k, 840k), rendered as a high-quality embroidery down one side of the front panel. It's a piece of designer Bitcoin headwear on a premium, classic trucker cap.
