Do you remember what you did in 2011? I'm sure this former employee of ABC News still does.
He used a lot of the ABC servers to mine some Bitcoin to make use of idle CPU power. Of course it got him fired, but what still cracks me up is the journalist' statement on what a stupid thing it was to do:
Bitcoins can be traded for cash, with the currency having reached highs of around US$20 per coin. I’m sure the consequences the unnamed employee now faces for using company equipment for personal gain aren’t going to be worth the effort.
This guy mined some bitcoins when there were worth $20 per coin
