I am actually running ads on various page but it doesn't give me up to the results I want, sometimes I use 1k daily, despite that I do have 5 likes, 3 comments a day. So I bought a course from a mini-importer whose page is a Wow, I mean the man is a boss in the business. I ran the video ads according to what he taught me in the course, No results at all. so he said I should try to change my currency to dollars and I should use that to run the ads.
So I wanna ask is that true?
