Offering a shortcut to skip all that and pay for growth seems like a common sense move for a lot of small creators. I struggle to think of the arguments against it - are they concerned big creators will flood money into it and drown out smaller ones? They already drown out smaller streamers, especially in streaming categories that are very "saturated." They also have no incentive to boost their stream, they're already top of the recommendations anyway.
Great revenue idea, and a change I as a small creator was welcome to see. Often I have viewers want to spend their channel points or bits or whatever they're called and I tell them to save it, I don't seek profit off of what I do (plus twitch takes it all anyway) I have a day job - but I do feel bad because they seem to want to spend it on something and I only have enough energy and bandwidth to add custom emojis or bot commands, which are dumb and people tire quickly of anyway.
Bits are purchased at roughly a 100:$1 ratio, and about half of that goes to the streamer (and half to twitch).
