We've told you about other wild uses for blockchain technology besides bitcoin: mortgages, weddings and more. Now it's time to go down the cryptocurrency rabbit hole — or maybe the bitcoin mineshaft? Joon Ian Wong is managing director at cryptocurrency news site CoinDesk. He takes us back to his reporting for Quartz on a bitcoin mine in Inner Mongolia, which is both a very real place and yet very unlike other types of mines. Then, all of you tell us where you've seen bitcoin (and bitcoin scams?) in the real world.

Update (7/18/2018): A previous version of these show notes misstated Wong's title at CoinDesk. He's managing director.
