Egirl just chatting streamers like Amie, that grow fast mainly based on being good looking & female don't usually grow past 200-500 viewers & last 2-4 years. Especially if they start making more money on other sites like Passes, OF. They get lazy on Twitch. Why stream 6 hours a day when they can take a few selfies and make more.
When they get lazy, regulars leave. Why sub to someone that is super inconsistent like Amie. Or some get lives, GFs, jobs and move on. And new viewers look for new streamers that are excited to be streaming & on all the time vs half assed lazy streamer like Amie that is never on.
