[tangrufus]

Cryptocurrency should be transparent. So does the mining tools. This Chrome extension(https://cnhv.co/asvu) will always tell you who you are mining for.

Features:

 - Always tell you who you are mining for
 - Immutable from other ad blocker extensions
 - Automatically pause/resume when internet offline/connected
 - Use official Coinhive JavaScript miner library (https://cnhv.co/ax6k) directly
 - Mine for second user

 - Extension on Chrome Web Store: https://cnhv.co/asvu
 - Source Code on GitHub: https://cnhv.co/as0d

You shouldn't trust a random developer on the web, i.e: me!

 1. Check the source code
 2. Verify the extension source code hosted on Chrome web store is the same on GitHub (Tips: Use http://crxextractor.com)

Feature requests and suggestions are welcome
