This week, we talk to Paul Vigna, one of the coauthors of the new book "The Age of Cryptocurrency: How Bitcoin and Digital Money Are Challenging the Global Economic Order." Vigna tells us how Bitcoin is growing up, becoming more than just a fringe currency and turning into a potentially major factor in the international economy.

Plus, we'll tell you what to think about Google's $900 million investment into SpaceX, Apple's record-setting profits, and FCC Chairman Tom Wheeler's newfound love of net neutrality.
