I guess you are talking about fixed/old subs? Because @actually already mentioned 60 - 160 in cheers and subs (I don't know if he meant per day or per Darks two daily streams). Even with 2500 / month on top, that would bring the cume to 140 - 240 (or 200 - 400) max/day. I still fail to see how Twitch makes 100 - 300 per day from this?You're not counting the $2500 a month he's bringing in in subs.
Edit: I just saw the posting from @BrunoMattei : so Twitch takes in 50% of the money coming from subscriptions? Wow! I was thinking about something like 10% or so. But that's... hoo.
