Web Mining – Monetize Your Website through User Browsers

Last updated on:
Fact Checker

Coinhive is a Monero (XMR) miner that runs on users’ web browsers when they’re visiting certain sites (don’t worry, we don’t employ this on 99Bitcoins). Recently, The Pirate Bay and CBS’s Showtime were busted for running Coinhive on visitors’ browsers without their knowledge or consent.

Before we get into a discussion about how to use Coinhive to monetize your content, let’s first discuss why website owners might want to use it instead of the tried-and-true method of online revenue generation: ads.

The Rise of Ad Blocking

Software that blocks online advertisements—usually referred to as an ad blocker—is rapidly becoming the standard. According to PageFair, a company dedicated to analyzing and mitigating this trend, about 615 million devices were using ad blockers at the end of 2016. The total number of internet users in mid-2016 was estimated to be 3.4 billion. This means that around 20% of users employ ad blockers.

Rise of adblocking

Because most ad blockers are free and easy to install, there are no immediate downsides—and plenty of upsides—for their users. The most popular ad blockers include Adblock Plus, AdBlock, and—my personal recommendation—uBlock Origin. Origin includes a filter for Coinhive to deny websites free access to your CPU’s mining power.

In addition to blocking ads and trackers via ad blocking methods, particularly proactive users may opt to go on the offensive with AdNauseam. This browser plug-in not only blocks ads but also spoofs clicks on them, generating false traffic to the detriment of advertisers’ conversion rates and thereby wasting their advertising budgets. The credibility and effectiveness of online advertising, in general, has been called into question lately by major companies such as Uber.

Because the current business model of the internet is largely based on advertising, ad blockers and the apparent decreasing impact of regular online advertising are forcing advertisers to adapt or go broke.

Cryptocurrency as the Solution

Because cryptocurrency is “the internet of money,” it will likely prove to be a better way to monetize the internet.

The Brave Browser is one attempt at a solution. Brave automatically blocks ads, or at least replaces them with privacy-respecting ads. Brave allows users to earn small amounts of bitcoin if they opt in to viewing these “good ads.” Brave also lets users fund participating websites by automatically allocating bitcoin donations based on the amount of time they spend on each site. Brave is improving quickly, and it will hopefully soon incorporate Lightning Network micropayments.

Coinhive presents a more straightforward approach to content monetization. The integration of the Coinhive script into a website gets the CPUs of cooperative visitors to mine Monero. All proceeds are split between the site’s chosen Monero address and the Coinhive creators, who receive 30%. This is a fairly large cut, but an open-source version known as Harvest, which will allow site operators to retain the full proceeds of mining, is likely coming soon.

Depending on the number of visitors a site receives and the time those visitors spend on the site (and the XMR price and mining difficulty), profits from Coinhive may allow a site to forego other monetization options such as ads, paywalls, donations, and subscriptions.

Coinhive web mining modes:

Coinhive’s web mining functions as follows:

1) As a Proof-of-Work “Captcha” that performs a set number of hashes or as a continual process. Unlike a regular captcha, this mode is unable to distinguish humans from bots. However, it is effective at rate-limiting actions, and it represents a great DDoS or spam countermeasure. Provided the cost of the mining is higher than the reward for spamming, bots will have no economic incentive to target a website.

2) As an automatically redirecting Proof-of-Work shortlink using the cnhv.co prefix. The number of required hashes will determine the degree of delay before the shortlink redirects, although the time value will vary according to the CPU power of users.

Shortlinks are especially useful for sharing links over social media, particularly on Twitter due to its limited character space. Here’s an example, which redirects to the Wikipedia entry for Monero: https://cnhv.co/6bk.

Tip: The new Coinlink site allows anyone to earn XMR by creating and sharing a Coinhive shortlink.

3) As a continual mining process. This mode is optimal for sites on which users spend a lot of time doing things such as browsing content, reading articles, watching videos, or playing games. Here are some examples of sites that have implemented this method:

  • Windscribe, a VPN service, uses Coinhive to let users earn account upgrades and bandwidth.
  • The Defeating Aging site uses the web miner to generate charitable donations to the SENS Research Foundation.
  • A college professor set up a simple web mining page for anyone who wants to contribute hashes to his Tesla fund.
  • Faucets that pay out in Bitcoin and Monero based on XMR mined are available.

Coinhive’s flexible code allows for nearly unlimited creativity when it comes to implementation.

Web mining via user browsers

Continual mining, or web mining, is by far the most profitable approach. If a site is able to retain numerous miners’ time, it can expect to earn a decent amount of XMR. Approximately 0.3 XMR, or $30 per month, is estimated for between 10 and 20 steady miners.

Note that the level of CPU usage is customizable. CPU usage should be set at a reasonable level, or it will noticeably slow down users’ devices and cause them to abandon a site.

Coinhive web mining should also be announced to site visitors to prevent any backlash or malware accusations. Ideally, web mining should be an opt-in process. Laptop users may be particularly aggravated by a site that surreptitiously drains battery power through mining. Configuring the miner to halt on low battery power could avoid a lot of PR difficulty.

An open-source plug-in is also available for Coinhive in WordPress. This can be configured to start automatically and run without any widget’s being visible.

Why Mine Monero?

If you’re wondering why there’s nothing similar for Bitcoin, it all comes down to Monero’s ASIC-resistant algorithm, CryptoNight. This algorithm ensures that, unlike Bitcoin and most other cryptocurrencies, Monero can be mined more or less profitably on the average desktop or laptop CPU. While mobile devices can also mine Monero (and run Coinhive), they’ll produce a very low hash rates.

If you’re interested in directly mining Monero, be aware that Coinhive’s 30% cut and the inefficiency of JavaScript CPU-mining (65% of a regular CPU miner) make it an unprofitable option. GPU mining on a reputable Monero pool (avoid Minergate) will net far superior results.

Advantages of Coinhive

  • It’s easy to implement and configure on most sites.
  • It respects user privacy and allows sites to do away with tracker ads and the like.
  • It is entirely unobtrusive and doesn’t interfere with the design or user experience of a site in any way.
  • It achieves the best results when run over long periods of time, incentivizing sites to produce high-quality and engaging content rather than the clickbait model incentivized by ads.
  • It is fairly transparent; compare the pool’s mining results to your data to verify the results.
  • It will serve to introduce new users to cryptocurrency.

Disadvantages of web mining

  • It’s already blocked by many updated ad blockers (and all JavaScript blockers), and certain antivirus programs also flag it. Site owners will have to request that certain users manually enable web mining in instances where it’s required to access content.
  • Unless a site is popular and enjoys high retention rates, it’s unlikely to earn much revenue from web mining.
  • If not properly configured for older CPUs and mobile devices, web mining can slow down users’ devices.
  • There’s a high potential for abuse by malware developers and unscrupulous operators.

Having delved into futures trading in the past, my intrigue in financial, economic, and political affairs eventually led me to a striking realization: the current debt-based fiat system is fundamentally flawed. This revelation prompted me to explore alternative avenues, including investments in gold and, since early 2013, Bitcoin. While not extensively tech-savvy, I've immersed myself in Bitcoin through dedicated study, persistent questioning, hands-on experience with ecommerce and marketing ventures, and my stint as a journalist. Writing has always been a passion of mine, and presently, I'm focused on crafting informative guides to shed light on the myriad advantages of Bitcoin, aiming to empower others to navigate the dynamic realm of digital currencies.

  1. I have been using Coinhive on my popular site (25,000) month views and over 3 months earnt £00.0007 nearly 1 thousandth of 1 penny. so I’m dropping it as a bad idea.

    1. Hi Lojanus,

      That does sound very low. I’m sorry it didn’t work out for you. What settings were you using for Coinhive?

  2. If you read “avoid MinerGate” thread carefully you will find out that there’s no reason to do so. There are some people sharing unconfirmed allegations probably taken from some other threads on the Internet. I really can’t understand how this specific thread can be used as a legit reason to avoid such good service as MinerGate.

  3. I think there so many services like Coinhive but better, Gridcash for example. 30% fees is too much and antiviruses and adblocks often react.

    1. Hey Karim,

      You want to just leave your PC to mine in the browser? You can do that but it won’t be nearly as efficient as mining on your PC using a Monero miner. Check out Monero’s latest GUI wallet which includes a mining tool for CPUs.

      1. Hello Steven,

        no i mean to do web mining like how some faucet do while waiting for timer reset and share profit with people who mine, but instead of having faucet just have the browser mining and share profit with everyone who leaves the browser running etc, know what i mean?

        1. Hey Karim,

          Sure, you can make a faucet out of this. Combining it with ads and offers could work pretty well. It should be pretty easy to setup a site like that and test it out. You should let people know that webmining is taking place but I think many would be happy to allow it, if your faucet pays out better than others.

  4. idk if its just me, but this seems like a scumbag thing to do use visitors/members, it really does i own a website with many visitors and i would feel like trash if i did this,

  5. Hi Steven,

    is there any way to use website to mine litecoin or similar currency?

    For example would site with 45-50k users per day with average time on site 35-45 minutes could make any bucks with CoinHive and could it be set how much CPU is allowed to use so i don’t end up using 100% of my users CPU-s?

    Thank you

    1. Hi Mark,

      I doubt it, as this wouldn’t be an efficient coin to mine with user CPU power. You see, Litecoin’s Scrypt algo is mined by ASICs (and perhaps some GPUs still), which are many several of magnitude faster than CPUs for mining. I think only coins which are CPU mineable are suitable for this sort of thing, although it’s possible someone will develop a version which works for GPU-mineable coins too.

      I think with visitor stats like that, you could well make some decent money from webmining. You can indeed set the intensity of mining so that people’s systems don’t get sluggish (this would obviously discourage them from visiting your site).
