Amateur hour is overhttp://arstechnica.com/information-technology/2014/03/meet-the-manic-miner-who-wants-to-mint-10-of-all-new-bitcoins/At any given time, Carlson's goal is to account for seven to 10 percent of the entire world's Bitcoin mining as measured by processing or hashing power
The first rigs were delivered in July 2013 after about a year of planning, board design, and manufacturing (more technical detail is available here). Carlson's team achieved its first "petahash" of mining power—a thousand trillion or quadrillion hashing calculations per second—in January. It's up to about 2.2 petahash now across two facilities in Washington state and a third in Poland.
Toward that end, he's soon opening a third facility in Washington and rolling out a new rig design. The current rigs each contain 16 boards, with each board containing 16 BitFury chips, for a total of 256 mining chips on each rig. Carlson said about 90,000 processor boards have been deployed, which would put the number of rigs at about 5,600.
A new board MegaBigPower is designing will have 756 chips on each rig instead of 256.
Right now, MegaBigPower can mine 7,000 to 8,000 bitcoins per month, he said. Bitcoin to dollar exchange rates go up and down all the time, but at a price of $585 per bitcoin, that's $4.1 million to $4.7 million. When Bitcoin prices topped $1,000 in January, the monthly yields were worth up to $8 million.
Part of Carlson's business has been selling mining boards online. He's still doing big shipments—including a $5 million deal with Bitcoin investment fund CoinSeed—but he's pulling back from online sales.
"I figure I spent about $1 million building the existing facility and racking and deployment of the mining hardware, and then we probably spent in the range of $2 million to $3 million on the hardware itself," he said. Rent is another $8,000 a month, power $40,000 a month. "I think we spent probably $3 to $5 million dollars total on the operation. It's paid itself off [in bitcoins] many times over already."
While Carlson may run the biggest Bitcoin mining operation in North America, he's "fairly certain" that the creator of the UK-based BitFury is operating at a larger scale.
