The booming stock market of the 1920s had the New York Stock Exchange. The tech bubble of the 1990s had Nasdaq and E-Trade. And the virtual currency market of the last year has had Coinbase.

While there are many Bitcoin exchanges around the world, Coinbase has been the dominant place that ordinary Americans go to buy and sell virtual currency. No company had made it simpler.
