Dave Carlson is running one of the largest Bitcoin mining operations there is.

He's set up an army of number-crunching computers in two warehouses at an undisclosed location in Washington State. The computers generate a ton of heat and burn through electricity, but Carlson says he's generating $8 million worth of Bitcoin per month!

He invited KOMO News, a local Seattle station, to come check it out. You can see he's got quite the setup:

Carlson's space is filled with computer boards, each housing several chips that do the actual Bitcoin "mining."
