Just saying this now, you may disagree with my ideas and tips about how to be popular. These tips helped me become semi popular on youtube (still working on it)
Tip 1. Get a good microphone (nobody likes hearing people with bad microphones, it makes people turn off your channel)
Tip 2. Get a good recording software (I suggest OBS, but there are multiple others out there)
Tip 3. Make a youtube channel and personalize it (Make banners, and other accounts like twitch, and twitter)
Tip 4. Record a first video (Try doing something different, something nobody has done)
Tip 5. Edit your video (There are multiple editing softwares out on the internet you can use)
Tip 6. Quality not quantity (If you create a bad video people will skip off of it, but if you make a good video with NEW idea's they might subscribe)
Tip 7. Make tons of GOOD videos (When you start out post tons of videos)
Tip 8. Talk to the community and do what they will enjoy
Tip 9. Never give up! (HATERS GONNA HATE)
Tip 10. (INSERT NEW TIP HERE)

NOTE: This can be applied to things other than minecraft
Actually, don't even bother with minecraft anymore - 95% of the current minecraft youtube community is 15 or under, therefore tight on budget, leading to awful quality. Not to mention that many just do it for the money, and really don't care about anything else.
