Introduction

As most readers are well aware, market return data tends to have heavier tails than that which can be captured by a normal distribution; furthermore, skewness will not be captured either.

While I was at the Strata conference in Santa Clara earlier this month, I had the pleasure of dropping in at BigData Silicon Valley for a theCUBE interview with John Furrier and Jeff Kelley.

But if you want some, several online exhanges will let you buy BitCoins for real money.
