Is it really interesting to buy YouTube subscribers? Youtubers are people who have a certain influence in their sector (hence, if they reach a certain popularity, they will end up calling themselves influencers). When you reach a certain number of views, many people will want to subscriber you to find out what your secret is, in addition to knowing more about the content that you usually share.
Therefore, the answer to the question we just posed should be YES. It is the perfect formula to achieve the popularity you are looking for, to give it the boost your channel needs and that, from that moment, it does not stop rising in terms of followers and views, in the same way as the other metrics they will follow the same path.
