The concept is based on spending thresholds that unlock different reward tiers. As viewers reach higher milestones, they gain access to exclusive perks such as discounts, bonus bits, or entries into giveaways anything that could enhance the viewer experience, encourage engagement, and reward loyalty.

I really think it could be an interesting way to strengthen viewers sense of belonging, both to their favorite streamer and to the Twitch platform.
On top of that, it could provide a unique incentive for viewers to stay engaged on Twitch 'cause, after all, it's something important since we care and believe in Twitch above all other streaming plateforms. (Of course, while still respecting and valuing other platforms)
