I believe that some third-party affiliate marketers must have built business out of it by having employees
The chances of someone become successful on affiliate marketing is high when they are an influencer so in any form they establish them with certain people on social media via Instagram videos or any kind of content then they might start promoting products related to their content and make tons of money but for someone who wants to start from nothing, no fame then I would say it kind of wasting the valuable time.
