So, this movie will be a documentary movie? I don't like this kind of movie so much, cause I can't understand it. And this movie is about BTCitcoin, so it will be hard to understand 
I was thinking more of a drama movie. You'd have to fill in and and add creative twists to it, especially concerning Satoshi since we don't know much(anything) about him/them/her. It'd be like those movies based off a true story.
