After selling his dot com company in the late nineties for $5.9 billion, Cuban has been able to live large. And live large, he has.
One of his biggest purchases was a majority stake of the Dallas Mavericks, and ever since, he's become a huge voice in the sports world.
What does it feel like to be a billionaire? Cuban told James Altucher on a podcast:
"The billion was, 'I can't f---ing believe it.' Literally, I was sitting in front of a computer, naked, hitting the refresh because we were close - waiting until my net worth hit that billion when the stock price got to a certain point, and then I kinda screamed and jumped around and then got dressed."
