Yeah, it's getting easier and easier to make money on there. They've continually lowered the standards to monetize channels. It's easier than on YouTube. Basically all you need to monetize your channel is 50 followers and 3 concurrent viewers. You need 1k subscribers and 4k watch hours on YouTube. It used to be you needed 500 concurrent viewers in order to monetize.
Now you only need 75 concurrent viewers to get partnered. And almost all partners get invited to their new ads incentive program. You get a $100-$500 incentive depending on how many ads you agree to run per hour on your channel. This is in addition to whatever other ad revenue you get from them running ads on your channel. And if you generate more ad revenue than the incentive than they give you more. You get a 55% split of the ad revenue.
I know a guy who's a small streamer. He's been partnered for 6 years. He's doing the ads incentive deal. I'm pretty sure between Twitch and YouTube he's making low 6 figures. He was able to payoff ALL of his student loans in just a few years. If you can get 1k subs on Twitch, that's over $30k/year in sub revenue alone. Besides donations, bits, ad revenue, sponsorships, etc. He's even gotten some consulting gigs from developers because they help them find glitches or other fine details within games.
