Bitcoin Mining JavaScript – The Only Guide You Need in 2023

Bitcoin mining went through a lot of ups and downs since its beginning. Back then, it was hard and you needed to be technically advanced.

Luckily for us, in 2017/2018 we saw a lot of new user-friendly tools. We’ve got several great GUI miners, as well as an “innovation”- Bitcoin Mining with JavaScript.

How does mining with JavaScript work?

JavaScript probably isn’t the best language to write mining software. But it works well for coins such as Monero and WebChain, both of which have CPU-friendly algorithms.

GPUs don’t have a big advantage over CPUs when mining Monero, so someone came up with a good idea. Mining cryptocurrency with web browsers, through software written in JavaScript.

It took them some time to figure it out, but eventually, the software stabilized and started making huge profits for webmasters with lots of visitors. And that’s what makes it so interesting:

Bitcoin mining with JavaScript mines through your visitor’s hardware

It’s as simple as getting a code in JavaScript and embedding it in your website source. If you ever had a website, this is the same process as installing Analytics, Pixel, or Ads on your website.

With such practicality, a wise webmaster can easily spot this as an ad alternative. And depending on the type of content and the number of visits- this can be a much more profitable alternative.

JavaScript mining vs Ads

  • JavaScript mining can run along with Ads. Even if you have ads on your website, that doesn’t mean you can’t use JavaScript mining as an additional earning strategy.
  • Same as ads, JavaScript mining has no costs. If you already have websites and visitors, you don’t need additional investment. You just add the mining code to your site and hope you’ll have as many visitors as possible.
  • In its simplest form, JavaScript mining comes without the user’s consent, but we can say the same for ads. However, JavaScript can use visitors’ hardware to a much higher extent, so you can read on to a chapter dedicated to this.
  • JavaScript mining benefits from a lower bounce rate and longer stays on the website, more than ads do. I don’t know the relationship between longer stays and the number of clicks on ads. For JavaScript mining it’s simple- the more the visitors stay, the more they mine for you.
  • JavaScript mining doesn’t care about geolocation. No matter where your users are coming from- if they have the same CPU, they will earn you the same amount of cryptocurrency. And this is great for the monetization of websites with visitors from countries that have a low paying click/earning ratio.

With all this in mind, I like to think that Bitcoin mining with JavaScript is very profitable. If you don’t have any additional costs, then no matter how much you make is a profit.

The most beautiful of all is that JavaScript mining can be used on any website, with any amount of visitors, any bounce rate, and any type of content.

And as mentioned before, JavaScript mining makes great sense on many websites. Like in countries with cheap clicks, as well as for webmasters that have a hard time getting high-quality ads. By this, I mean “grey” areas with enormous traffic potential- adult websites, streaming websites, etc. Websites as such are not allowed to use AdSense for example. That’s where JavaScript mining can be used in addition to cheap ads, or as a sole income.

Still, some of you may get discouraged by the earnings at the current crypto market price. Even though it “works” on any website, mining with JavaScript is proportionally tied to the number of visitors and the time they spend on your website. In other words, you can expect some big money only if you have lots of visitors and they spend a lot of time on your website.

I think JS mining is a great idea. I don’t use it on this website since it’s still new, but I think this can be a perfect earning strategy for websites that offer to stream and/or have tons of visitors.

JavaScript Bitcoin mining – Is it ethical?

Most critics I saw on JavaScript mining are related to user consent and ethical problems tied to it. And it is true that any webmaster can embed the JS mining code into its website, without the user’s consent. But the same holds for ads- you can embed the ads code, and you don’t need to get a user’s consent before showing him the ad.

Plus, you’re using the user’s hardware and bandwidth to display your ad, while trying to persuade him to click on it and bring you a profit.

The only difference is that JavaScript mining is not visible on your page, plus you can use your visitor’s hardware to the max. Ads are visible on your website, and they take a very small portion of your visitor’s hardware power.

That’s why JavaScript mining went through a hell of ups and downs itself, with many people hating and some adblockers and antiviruses blocking the scripts of several JS mining companies.

How to make JS mining Ethical

There will always be haters, but if you think about it, this is easily achievable:

  • Get user consent. User consent is the one and only thing required for JS mining to become ethical. If you explain to your visitors that by proceeding to your website they are going to mine with their web browser, then there is nothing unethical about JS mining on your website.
  • Go a step further and allow them to deny. If you also allow your visitors to say no to JavaScript mining with their browser, then you may even become an angel compared to marketers that drop ads like bombs on their visitors. If you don’t want to become an angel, you can even disallow access to your website for those who don’t want to mine for you. It’s your website and your rules, just make sure you don’t do it without their consent.
  • Don’t be greedy. For me personally, this is a very important one, although you may feel different. Most JS miners provide the intensity parameter, allowing you to set a percentage of visitors’ CPU power usage. This gives you the freedom in choosing how much you’re going to affect their performance. My rule of thumb is up to 50% on non-greedy(light websites) that are primarily text-based, while I like to go as low as 20% on resource-hungry websites like streaming.

If you’re serious about your visitor’s satisfaction, you can even make something like a donation system. It’s not hard to get the user’s consent + allow him to choose how much of his hardware power you can use.
