http://www.vox.com/2014/9/5/6086171/why-im-investing-in-bitcoinsThis isn't the first time I've invested in the cryptocurency. In early 2012, I bought some bitcoins for around $7 each. I held them until May 2013, when I took a new job at the Washington Post. The Post's strict ethics rules required me to sell them for around $120 each. That proved to be a huge missed opportunity, as bitcoins skyrocketed to more than $1000 before the end of 2013.
