BFL has made so much money on early pre-preorders that the btc value has increased so much they could afford to refund everyone, and mine themselves....
I'll choose to believe this as fact, regardless of BFL's actions.
Nonetheless incredible amounts of electricity (~1 GW/h) are wasted on mining Bitcoins which is basically spend calculating zillion’s of SHA256 hashes.
Failed. Source also failed (Virtual Bitcoin Mining Is a Real-World Environmental Disaster) With that, how much of a failure is this lightweight C# Bitcoin Miner?
