In it's current state, Steemit will continue to have issues attracting that crowd away from their precious existing social media/blogging outlets. There are other ways to get tips on these other platforms and are far less "scary" than buying into a cryptocurrency on some "shady" exchange they've never heard of located in some country they've likely never been to all while reading how Bitcoin supports terrorism on their current choice of outlets. ;)
Absolutely no way Synereo will gain any traction whatsoever.
