Here's what happened: in early 2012, he put all his money into Bitcoin. Then he cashed out when they peaked (probably around December 2013). Then he used the money to start yet another e-learning business/service.
I don't see what the point of this article is. He used money that was given to him to bet on speculate on a wildly fluctuating asset, and came out lucky. Now he's trying to invest his money sensibly. So what?
To me, the only interesting part of this article is that he pays most of his employees in Bitcoin. The rest is just fluff.
