Well, some streamers still use this and some of their audiences are using it too, I just find this idea good because it helps you support your favorite content creator and at the same time getting some reward for it. Maybe if they used bitcoin as a reward, I think many will flock.
Sure, I never said that literally no one would be using it and that it wouldn't gain traction. But then again, them conducting an ICO says a lot about the company/project.
