Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections!

As of January 2026, this "limited edition" (whatever that means) yo-yo was still widely available for purchase on the Internet from various retail websites. Came with gold colored string instead of the usual white cotton string. Collect & HODL Co., a subsidiary of ProSnacktive Sales LLC, partnered with Duncan Toys to unveil this first-ever Bitcoin-themed Duncan Butterfly XT yo-yo. The collaboration aimed to capture the essence of Bitcoin's market fluctuations and offer a playful representation of the Bitcoin journey. The Bitcoin-themed yo-yos were exclusively available for purchase on Walmart Marketplace. Based on the world famous Butterfly, the Bitcoin Butterfly XT featured modern yo-yo technology including a large ball-bearing axle, starburst response, and a take-apart design that allowed for easy knot removal. These features made the Butterfly XT perfect for beginner-to-intermediate players looking for high performance and quality on a budget.
