It can have bad effect but if we see the larger picture this will send crypto message across and crypto will become more popular and it will be talked in every household. So more people will research about it and more will join it. There are always two sides of the story so i would go with the positive one.
I didn't agree with it even you were saying it will send a crypto as a massive promotion to the people in the world but in reality when you were promoting something in a bad massage and it will bring the product to get a lot of negativity from the viewers.
It will bring a lot of negative opinions about ripple. Why didn't he just create a film about the bitcoin? That will much better rather than take the scam case called onecoin as a theme to be used as a movie.
That's crap.
