In Toronto we have put together a small group of artists that support each other and often book shows together. It helps to have others in the area since it makes it a bit easier to put together your own shows. If you don't know anyone in the area, try cultivating a community. Organize meetups or events where others can learn to use the tools and software, listen to chipmusic and get excited in general.
Blip Noir from Toronto only started doing chipmusic when I literally forced him to write a couple songs for a big outdoor festival that I was planning to be a part of. He showed up with a couple amateur songs but he was hooked and over time his music has become really, really cool.
Since you're young, you might be able to use your school to do some of this stuff. See if you can do a show at your school, if it's cool enough then people might get excited and want to do the same. Be open and supportive to help those who want help.
I've done workshops at the Ontario Science Center (just think science museum) where I've taught kids about making chiptune music and while that's not the most exciting thing for some people it's actually really rewarding if you've got some kids who are really into it and you're building up more local community.
