Oh that makes sense, in this case it would need something like a toggle to only share data on WIFI, kinda like Google Photos and Immich do

Maybe predownload videos on WIFI (Tiktok already has this function) and only use mobile data for comments and replies, and asking the user in case they are on mobile data if they want to download videos on demand.

Anyways, I was thinking on ways to make it work without the crypto while keeping the P2P aspect. Thanks for the explanation.
