There are thousands of websites mining cryptocoins. I recently posted a tweet that went viral in Brazil - it showed that one of their government sites was mining coins - and draining 360% of my notebook's CPU power:
Since that day, CoinHive has been removed from a lot of sites:
"In the 10/15 run, there were 1,040 mobile sites with the CoinHive Javascript embedded. In the 11/15 HTTPArchive run, this has dropped to 759 - a drop of 27%!" -- Rick Viscomi
To find all of these sites you can dig into HTTPArchive with BigQuery:
