If $5.99 or whatever buys 30 days of ad-free viewing (per channel), then being able to pay 100 bits for a single day of ad-free viewing per channel would be a massive profit to Twitch. I am not on Twitch every day and I can't be, so it feels like I am wasting money on a 30-day sub to someone, but if I can get ad-free for about $1 for just that day, then that is potentially $30/month spent instead of the $6 you would normally get. This seems like a no-brainer feature that would be massively profitable on your end, and massively more convenient for me.
