Great idea, I can’t wait for this approach to become more popular. I hope the rising popularity of Shadow DOM, along with 3rd party cookie blockage will help put an end to tracking, at least in technical terms.
I'm working on an app that lists odds from the following crypto sites:
1xBit
Betcoin
Betcris
Betonline
Bodova
Bookmaker
Cloudbet
FortuneJack
Intertops
Nitrogen Sports
Sportsbet
Stake
Thunderpick
The app works by scraping data directly via the users' computers and sharing it with other users (sort of like how BitTorrent, everyone fetches a small piece, together they make up a whole picture).
The app will be free and possibly open-sourced.
The app will be available soon (about 3-4 weeks), screenshots and early beta signup links are here: https://project-ze.ro/
