i also think arnold would be a good candidate, but for teens it's better to look at some young group or band that do music that are for their target and that can promove bitcoin, there isn't something better to encourage teens to embrace bitcoin
Why? Nobody can ever understand anything he says. I think ones like Nas and the Winklevi are great because they understand bitcoin for what it can achieve and have personally invested in it.
those are there more for the money, for themselves, they are not good candidate for rising the awareness about bitcoin, you need someone that is out of the context of bitcoin and that has a different influence on different type of people
those same people that do not care about bitcoin or don't know about it, you don't need a bitcoiner to promote bitcoin, you need a good non-bitcoiner for promoting it
