As you know some sites are already experimenting, CPU cycles in exchange for Ads using javascript. However on my battery devices I'm not sure how I feel if very many sites were using my CPU. My cheap devices have poor battery life as it is but other than that I say mine away!
Too good to be true. Most likely the outcome will be mining + ads. Why getting money one way while you can do both (secretly). All that in the name of "improving user experiences".
It's not a bad idea but how are you notified that it's doing it? If I leave the one tab open and start playing a game and it's lagging because i'm mining in the background.
My battery life and electricity bill is more important to me than their revenue. No thanks. Sites that would even consider abusing the user's hardware are likely to have bad ads too so frack 'em entirely. I read on reddit that some extension called iridium is considering a miner for monetization. Damn, I hate bitcoin.
That would be a form of malware, and no doubt they'll cry fowl when people disable the ability for them to do it especially antivirus companies. The other key point is that there still will be ads, and the profit from mining depends on the amount of mining being done. If it became common place on web browsers, they'd make bugger all on it and just p!$$ off the users through a poor web experience, battery life, etc.
Not to mention there's no guarantee what the javascript actually does, having hidden malicious code run at the same time. No.
CBS's sites are mining Monero, around 60% CPU usage: https://www.theregister.co.uk/2017/09/25/showtime_hit_with_coinmining_script/?mt=1506379755407
Someone wrote a chrome extension that is supposed to let you know if a website is mining when you visit it. --- https://chrome.google.com/webstore/detail/miner-detector/likbfajepcccjkogmjghenhpboggoglb --- I have not tested it myself, so use at your own discretion.
The source code is so unbelievably simple I cannot see it being anything other than what it says it does
The Pirate Bay enabled mining AND ads on their site lol! https://torrentfreak.com/pirate-bay-is-mining-cryptocurrency-again-no-opt-out-171011/
With sites like that, it is always better to assume malice and take the necessary precautions. And "ublock resource abuse" block list ftw!
