Which campaign is the most effective today?

I am looking to run crypto and credit ads. Which campaign is most effective for them. Thanks

Is it CPA? if it is then, you can go with YT ads. but make sure to choose placements ( avoid putting keywords. ). If you want to use keywords (in headings, description, or inside the video), then use Crypt0, bitc0in instead of the exact name to avoid instant suspension. These are the tricks that I had tried, and it worked for me.

if you run crypto try native ads
