First I want to apologize for my bad English.
My website uses a lot of videos and it is hosted on my server, my domain name uses CloudFlare CDNs for the purpose of increasing security (Hide real IP and use SSL).
I also know that Cloudflare will not cache large files.
The above image statistics I see is that " Uncached Bandwidth" so Cloudflare will not save large files of my video (I don’t want Cloudflare to save it), it will not affect Cloudflare much and I will not account locked? As I said I just want to use it for more security.
