Zcash mentioned in 2017-11-27 Wall Street Journal

Cumberland (owned by high frequency trading firm DRW Holdings) mines Zcash:

“Cumberland mines Zcash, an upstart digital currency whose backers say it has better privacy protections than bitcoin. Cumberland is tight-lipped about its mining operation, saying only that it is located in the U.S. near a low-cost source of hydroelectric power. Cheap electricity is essential for cryptocurrency mining to be profitable.”
