If you're eager to regularly support a partnered Twitch streamer beyond the usual $5 per month subscription, you don't have many options. You can send them some bits, of course, but you're otherwise left contributing to a Patreon campaign or some other outside fund. However, you'll soon have a way to show an extra level of kindness. Twitch is launching an opt-in subscriptions beta that adds $10 and $25 monthly options. Naturally, it's not just the stream host that benefits -- you'll get some perks as well.
