How to mine Bitcoin

Coinhive is one of several services which offer JavaScript that can mine for cryptocurrency without the users' knowledge or consent. Coinhive is one of several companies offering this technology, but it is currently the most popular.

Pixalate has compiled the list of sites with Coinhive enabled. You can download the list here. The list was last updated on November 27, Cryptojacking occurs when a JavaScript tag is integrated into a website's code to utilize the visitor's CPU to mine for cryptocurrency — such as Bitcoin, Monero, Ethereum , etc. The above image is an example of a code in which the publisher controls how much of its visitors' CPU to utilize for mining set by the throttle number.

The website owner — and the script provider — are paid, while the user typically does not benefit. In fact, if the script uses enough of their CPU, the quality of their browsing experience is likely to be reduced. Watch what can happen to your CPU when you visit one of the sites in question:. If a website helps crack the encryption, they get paid. The murky area is that users might not know their computers are being used in this way.

And there is plenty of overlap: In many countries, posting a Privacy Policy online is required by law. Many of these sites are also ad-supported, which also requires a Privacy Policy for tracking purposes.

Having a Privacy Policy is common practice among legitimate websites. Even basic website tools — such as Google Analytics — require a Privacy Policy. The lack of these basic, and sometimes required, website items can be a red flag.

Some big brands are appearing on these sites, and the ads are being served by some of the world's biggest ad exchanges. Here is just one example:. It also has Coinhive enabled. As you can see, an ad from a premium brand has been served to this site.

The user experience can be drastically impacted, in a negative way, as a result of their hijacked CPU. Many of the sites are cluttered with ads and auto-play video ads that are difficult to close.

Given the current climate in the industry around brand safety, transparency, and general quality, we urge marketers to carefully scrutinize the list we have provided and optimize your campaigns as appropriate. In some cases, the websites are giving the user something of "value" as it relates to that particular site. They may be rewarding visitors with digital currency to spend on a game or on the website. The purpose is to incentivize users to stay longer, which therefore allows the site to use their CPU for longer, which earns the site more money.

As the above video illustrates, Coinhive pays 0. In order to reach 7. This equates to device seconds per visitor.
