Fortnite players are seeing an increase in subs because of the Twitch Prime skins for sure. Everyone gets a free month trial, so all someone needs to do is activate the trial, and link their Epic account to the Twitch account. From there they sub if they want. Since I have Amazon Prime I've been passing my free sub per month from streamer to streamer. Sure most of these players will see a dip but I think Ninja will hold pretty steady, thought this even before last night. One of the reasons he is so popular is because he streams most of the day, typically 12+ hours so he gets a following from people all across the globe. As well as the obvious reason is his game play is entertaining and hilarious. Fortnite has also taken on some different form I haven't seen before, countless memes are popping up each second. Some people don't like Ninja's personality but a month or so ago he did a charity stream for suicide awareness and helped raise over $100k USD for a suicide prevention/awareness charity.
