Voted for I haven't made up my mind yet..
I don't stay for the money; I've never cashed out. But I came for, and stay for, the potential money. I enjoy the many benefits of this versatile blockchain so I might stay, but if the potential monetary gain became definitely zero forever, I'd have to rethink it.
Luckily, I doubt that will ever be the case. It would be really hard to tell if that was the case unless somehow the entire chain ceased to function. Perish the thought.
