Religion all over the world has a convincing force that either compels or changes the belief system of people. Using religion as a medium for Bitcoin campaigns, is a necessary means of creating a popular awareness to change the Bitcoin apathy in most people.
Religion understanding is never the main thing that prevents Bitcoin awareness and the last time I checked it the political understanding thats the main problem Bitcoin had.
Meanwhile, there's no need for any campaign for Bitcoin to gain awareness and I believe the crypto expo or blockchain event organized around the world is enough to generate Bitcoin awareness.
