Things I don't like :
1) Poor video quality
2) Distorted sound quality
3) No real content in the videos
4) Using YT to prmote FUD and pumps
Pls don't do any of the above and you will be successful.
Most YouTube videos these days are actually quite great quality. I mean considering they are mostly done by a small team of less than 5 people, sometimes only 1 person, it is rare to find truly terrible content on YouTube these days. It simply doesn't get views.
