"Banking on Bitcoin" is a helpful, critical look at cryptocurrency.

Unless you’ve been completely avoiding the news—and in dumpster fire of America that is 2017, I can’t blame you—you’ve probably heard of Bitcoin. You probably also have no idea what Bitcoin or “the blockchain” actually are. Then again, no one really seems to. Bitcoin may revolutionize the world or be the biggest financial bust since the Dutch Tulip mania. Either way, the “cryptocurrency” has skyrocketed in value in recent years leading to Bitcoin millionaires and such a scramble to get on the gravy train that people are even mortgaging their houses to buy Bitcoin. If you’d like to learn about the strange history of Bitcoin, and it’s possible radical future, you should watch Banking on Bitcoin, a 2016 documentary currently streaming on Netflix.
