How To Make a Bitcoin Address With a TI-89 Calculator

sarahnaomi writes: The power of Bitcoin is giving your dusty old TI-89 calculator a second chance of being useful. 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.

    I'm not rolling a die 72 times and manually entering each result.

      It's a bitcon article so asking if the suckers drawn in the scheme are retarded is considered rude.
      "It's the future" - it's like that thing in Cryptonomicon only not backed by anything of value and it's founder has gone into hiding.

      More importantly, calling people who use Bitcoin retarded or suckers doesn't actually constitute a strong argument against it.

      only not backed by anything of value

      Bitcoin is backed by the goods and services available in exchange of it, just like any other currency.

      and it's founder has gone into hiding.

      The founders of most currencies currently at use are dead.
