A website wants to user my unused computing power
This doesn't sound good. How does it do this? Anna Frodesiak (talk) 02:19, 26 February 2018 (UTC)
 * Apparently, it's a plugin, which should draw increased scrutiny because of the implicit permissions. But that wouldn't be necessary: JavaScript could compute whatever (though perhaps less efficiently) and then make a "request" back to the server that is actually just uploading the result.  I suspect it's a bit silly, since it's surely worth less than the electricity used to compute it: I'd guess a handful of cents per user-day, and people aren't going to be leaving those tabs open longer than necessary.  I have a hard time seeing more than a few thousand dollars per year even with a good uptake rate.  But maybe as a social statement it makes more sense.  --Tardis (talk) 05:19, 26 February 2018 (UTC)
 * Many websites mining (whether notifying users, secretly, or hijacked sites) use Coinhive which mines Monero (cryptocurrency). This very roughly estimates [//torrentfreak.com/how-much-money-can-pirate-bay-make-from-a-cryptocoin-miner-170924/] $12000/month for PirateBay. This estimates Coinhive themselves make "$3.7 million and $5 million per year" from their 30% cut for all websites. This person with a very minor website which people don't visit for long [//medium.com/@MaxenceCornet/coinhive-review-embeddable-javascript-crypto-miner-806f7024cde8] made $0.36 a day, which was significant less than they made with ads.Nil Einne (talk) 07:30, 27 February 2018 (UTC)
