Amazon S3 Data Transfer Out Costs for Mobile App for Videos

Question

I'm developing an android app which is in some ways similar to Instagram and will host videos uploaded by users. I'm using Amazon S3 to store my videos, and I retrieve the videos from my app using a generatePreSignedUrlRequest. The app is still in development mode, but I was already charge 0.10$ for "Data Transfer Out" of Amazon S3. 0,10$ is nothing, but I was thinking that if I open to the internet world and get even 1000 users, I couldn't manage the costs. I have read that using CloudFront beside S3 would make the deal cheaper, but it would be still very expensive. Is there any way to save money or should I try to get an investor (very difficult) or crowdfunding?

I have made a very hopeful estimation of my app which is not all that and might already destroy my plans in less than a month.

500 users (artists) and 500 users (watchers). 500 users would upload 20 video in average each month. Each video would be like in average 50Mb. So I would get 10000 videos on the platform and a storage of 500Gb, which is not that much. But if 700 users watch all these videos in a month period (around 7,000,000 requests)..I would get 300,000Gb transferred each month and I don't want to mention the bill. It would just be unacceptable.
