The main source of income for any Twitch streamer is subs, which are subscriptions that viewers sign up for. The motivation to subscribe can have different reasons for a viewer –
They want to support the streamer financially and help them grow, or they want to take advantage of the benefits the streamer gives them when they sign up for a subscription. So subs are paid subscriptions, 50% of the price of which goes to the streamer himself – but there’s a catch: the use of Twitch subs is so far reserved for Twitch affiliates and Twitch partners. To become an affiliate or partner, you have to have a certain number of regular viewers over a certain amount of time. So if you want to make big money with Twitch right away, you’re going to have to start thinking about how to build a steady and loyal community that will be willing to sign up for paid subscriptions for you.
