Ask yourself a serious question. If you have under 1,000 subs and under 4,000 hours of view time, and your channel is a year old, you are at BEST making about $1.00 a month from your channel. That may even be a high number.
YT is not hurting your channel by doing this. Youtube is weeding out thousands of junk channels and sub for sub channels that have nothing to do with you or your content. YT didn't yank your paycheck, stop feeding your family or hurt your lifestyle by doing this AT ALL.
The next question is this. If you can't get your channel over 1,000 subs and 4,000 hours of viewtime despite this new rule, do you seriously think you have the ambition and talent to take yourself to 100k subs?
Don't quit. And don't think this new rule is about you. It's about making YT a better platform FOR YOU once you hit those benchmarks.
