The ending is very depressing (in my opinion anyway).
Why? Without giving too many spoilers.
The first parts are really euphoric (blindly optimistic, positive, fun, exponentially progressing...). Then you start to learn about how this all is a big wild roller coaster in both monetary and emotional aspects (prices fluctuate, companies rise and fall while they steal your money and/or BTC and seemingly good guys face jail time, prices crash again, etc, so basically 99.9% of the people lose something or other at the end: time, money, coins, spiritual happiness, positive future outlook..., sometimes all of these at once).
The ending shows how Bitcoin sucked out most the enthusiasm from a main subject of the documentary who was probably one of the very few true Bitcoin supporters who never seemed to gave up. For me, it seemed like he feels really empty now, like he already lost the hope and he just fails to admit it for himself and move on, he just got stuck with Bitcoin but without the spiritual or monetary benefits.
Ahh...
That order I didn't place 1-2 hours ago (because I were listening to Schiff) would be in the green already.
Starting to feel like a real reversal to me.
