Some stories become legend. Mt. Gox taught us all about private keys the hard way, and this dad hat keeps that lesson front and center. The embroidered design hits different when you know the history.

Whether you're explaining "not your keys, not your coins" to a newbie or just want to rep one of Bitcoin's most infamous moments, this low-profile hat does the talking. The adjustable strap and curved visor keep it comfortable during those long conference days.

Makes an epic gift for the Bitcoin historian in your life or anyone who appreciates the wild early days. They'll get the reference immediately. Free shipping on all U.S. orders means it gets to your door without the drama.
