How WIRED Lost $100,000 in Bitcoin

Back in 2013, when you could still mine bitcoins at home, WIRED was sent a small, sleek mining device manufactured by the now-defunct Butterfly Labs. We turned on the Roku-looking machine in our San Francisco offices and allowed it to do its job. A small fortune was soon amassed, now worth around $100,000. Then, we lost the money. Forever.

Here's what happened to WIRED's 13 Bitcoins—and to the millions of others that have faced the same fate.

Stefan Antonowicz, WIRED's then-head of engineering, set up the miner. Robert McMillan, a former senior writer for WIRED (who now works at The Wall Street Journal), then wrote about it. "When we received that Butterfly miner, we had a new ethical question: What do you do with the proceeds of a review device that essentially prints money?" says McMillan.
