Question: what are bits and subs on twitch?
Answer: Bits are Twitch currency (1 bit=1cent) that you can buy to support streamers. Gifted subs are subscriptions that either you or someone else can buy for a viewer without a sub in the chat. These bits are worth $0.01 per bit to a streamer. So if you give them 100 Bits, they will receive $1 in revenue.
