I do not want to make anyone sad, but is it possible that only the big fishs in the game make money? Just For example, the people who promote adplexity or the founders of AdPlexity itsefls. Just imagine that this entire industry was just invented so we spend money on their tools. I have heard very rarely in this forum here that someone has actually earned a lot of money with CPA. In most cases, you have lost money. It's just a theory of mine. Of course it may be possible that I am wrong but have you ever made really big profits without investing a huge amount of money in tools? Its just an idea, so pls dont hate or anything like that. And sorry for the bad grammar, Im from germany.
