A percentage off bits for redeeming loot on a channel
Something new that "could" be added to bits is when any viewer redeems 1 or more loot with Twitch Prime on any affiliate or partner channel, that channel owner could automatically get 0.15% off bits per viewer who have redeemed 1 or more loot when on that channel. It would take 100 viewers redeeming loot to reach 15% off bits for that specific channel.
The cap of the percentage off bits for the channel owner could be 5%-15%. Once a channel reaches the cap the channel owner could have one-to-two weeks to buy the bits with a percentage off, from viewers redeeming loot on their channel (before it resets to zero).
A lot of streamers support many other channels and it's out of love that people cheer streams, so it could be a good thing to have another way to support your favourite streamer with Twitch Prime by giving the streamer a discount on bits.
