"Banking on Bitcoin" is a 90-minute documentary about how Bitcoin started and how it became what it is today. For me, it is a useful source of information for beginners, especially to understand the basics such as what Bitcoin is and how does it work. That's why I really think, this is a worth watching one.
Have you already seen it? What can you say? Do you think that such film can raise awareness of the trend? If you are yet to watch, Banking on Bitcoin is available on Netflix and YouTube. There are, for sure, free ways to watch it, up to you to search for it
This came out in 2016, you are a little too late to even search for it. Its just alright when it comes to information. There are a lot better documentaries around. "Bitcoin: The End of Money As We Know It", "Life on Bitcoin" and the first documentary I watched long time ago, Rise and Rise of Bitcoin.
