Jed McCaleb, a programmer bought the domain name, “” in 2007. He wanted to create a fan website for Magic: The Gathering Online, a fantasy cards game. Although, he launched his website in late 2007 but soon decided to abandon the project.

With no previous experience of financial management, Mark Karpeles lacked the necessary skills to deal with the massive financial surge faced by his exchange at the start of the bitcoin boom.
