While the documentary provided a lot of good "ideas" regarding how bitcoin and block chain technology work and can be used, I wish they would have gone into more detail than they did. But then, I'm a technical kind of person, so I like things to be explained in detail. I also agree with one of the other reviewers (posted review on 3/11/2020) regarding the value of bitcoins. In the video, they made it seem like Fiat currencies can (and have) dropped (drastically in some cases) in value in a short amount of time, but that currencies like bitcoin won't. However, if you sold something to someone (in December 2017) and got paid 1 bitcoin for it, you would have essentially been paid $20,000 (since that's how much 1 bitcoin was worth then). If you never touched that bitcoin (same as leaving your money in a bank) that same bitcoin 1 year later, would only be worth $3,000.
I really liked the documentary. It's informative, easily understandable, and explains the nuts and bolts of what digital assets like Bitcoin are, and the Blockchain. That said, it should be said that currently, Bitcoin, as with most "coins", is traded like a stock on exchanges like Kraken or Coinbase for example, and therefore susceptible to market fluctuations. Case in point, a week ago as of typing this, you could buy a single Bitcoin on an exchange for $9200 USD, and today you can buy that same Bitcoin for $7941 USD. Bitcoins value is, for the most part, still determined by the USD. It's only when max output is reached, that Bitcoin will establish it's own value.
