Matt Whitlock, who helped make one of the world’s first Bitcoin ATMs, is at it again. In a video posted on to Vimeo, he showed how using the calculator once only used for high school geometry and a 12-sided die makes a secure address for your Bitcoin account.
The video self-explanatory. Load up your calculator with the code, roll it 72 times and enter the number rolled into it. After that, the calculator pumps out a private key and address.
