As your camera fills up - where do you move your videos to? As your laptop fills up - same?

Why when reaching to 4 stage there's nothing? Where's the incentive to keep moving up? Also, I miss a Q&A section... I feel kind of lost... perhaps this community is more for professionals than beginners? To Alexa and it's creators I would recommend a bit more engagment for beginners... though I like the community. thanks

Hey ya'll. I have an existing channel, but I am going to start a new and totally different one in a new niche. I haven't found a lot of resources for how many video's to start with. Some say start with multiple so YT has more data for your niche. Then I have heard where if you have more than one, that viewers may get off to soon and YT will give you negative marks. What's ya'lls opinion including Alexa's. Anyone had success with multiple vids to start and if so how many? Dropped at once or scheduled over how long a period of time?

What has been ya'lls experience with posting a link for your video to other social media, et al., Facebook, Instagram? Does it help, hurt? I've seen some creator mentors that say it hurts? What timing has been helpful or hurtful?

Ok I just told someone that my goal was to get monetized on YouTube and they asked me “How much can you earn from YouTube monetization?” And I honestly don’t know. How do I answer that question? I should know but I just don’t.
