Advertising would be great, no idea if that is a goal of theirs. Would be neat, though. If you ever wanted to earn revenues that way, just find a decent program to sell. JerryBanfield sells his courses, and uses his social media to promote it, works well for him.

I was doing great promoting Genesis Mining and making decent money, but I stopped because I decided it was not the best for my viewers to be getting into... better to just own crypto. Steemit in the end will pay better than Genesis Mining. That said, when my game project launches, I might do some cross promotion with it.
