Hi Folks,
 
I made a movie about Bitcoin's underlying technique.
Since English is not my native language, I would be glad if you watch the movie and give me some advice if necessary.
Currently the film is accompanied by an automatic voice. I'll change that later as soon as I know that the text is somehow understandable.

So, its still a draft:

Thanks for any feedback.
