Saying that streaming for coins is a bonus is the same as saying getting AP/coins/boxes is a bonus for playing for 10minutes and then going afk(which is how majority of people get these rewards).
Instead the streamers have it 10x harder. We have to be constantly going at it for 2hours without having to take a dump or else we'll be at the risk of a report. Not to mention we contribute more to the server. I understand that there are barely any views. But it's definitely better than if there wasn't a stream up for the game.
This is unrealistic in my opinion. I don't get on, see someone else already streaming, and then decide that i'll come back on later so that i can stream. I'll just fk it and not stream. Players don't schedule/postpone when they want to play gunz.
You don't have to change how the rewards work. It can stick to it being only rewarded to one person. But i think doing something like this https://imgur.com/a/wOvWdHH gives people variety. Too many times where i decide to stream but find someone else already streaming on the webpage streaming training rooms.
If you still think its a bad idea, at least adjust how the rewards work. Every 1hour - 25c, 2hours max. It still stays the same but this interval gives other streamers a chance to stream. Constantly gameplaying for 2hours straight isn't realistic with the servers current position. Heck constantly gunzing for 2hours is already super hard.
