Karpelès looking wistfully out the window

Mark Karpelès, or MagicalTux, is the current owner of the Magic the Gathering Exchange, also known as Mt Gox to obfuscate the fact that they use code originally designed to trade children's playing cards. With a unique style of brazen lying and complete incompetence, Karpeles has seized control of the Bitcoin Exchange market, with a volume nearly 200 times more than any other exchange.

While Karpelès is originally French, he currently resides in Japan where due to their love of foreigners and high tolerance for rebellious activity, he operates his exchange with impunity from the law. This is expected to never change.

Karpelès has appeared as a guest on The Bitcoin Show twice, although his first appearance he was too busy to come to the Skype camera.
