Thieves steal 600 powerful bitcoin-mining computers in huge heist In Iceland, police are hoping a power surge will lead them to the criminals' stash. https://www.cnet.com/news/iceland-big-bitcoin-heist-cryptocurrency-mining-computers/ "Icelandic thieves steal 600 Bitcoin mining computers, estimated value $2 million... $50 million... $2 billion... $323 million... $10 thousand"
