No its not worth it. They're not real views so its not going to be any different than getting 5 views per video. Comments and likes are what get your video suggested to more of the popular videos like Vanoss or Pewdiepie. I've learned from experience. Plus you're going to possibly feel like shit after getting so much views that you paid for and not getting as much as half on ones you didnt. Just go legit, it makes you feel better about yourself that people are actually watching your content. If anything pay to get your video to get advertised on youtube so you know actual people are watching it and plus you'll get more exposure.
