Frequently Asked Questions

Common questions about SpareChange - A Miner for your Website

Browser based mining is a method of mining cryptocurrencies using javascript that runs in your browser. Because it runs inside your browser, there is no need to install a program on your computer. Upon loading a webpage, a javascript program runs using a small amount of your systems resources to mine cryptocurrency that is typically paid to the owner of the website the miner is running on.

No. Despite what lots of media outlets are saying, browser based mining is not malware. It does not attempt to gain access to information on your computer or damage it in anyway. It is being referred to as malware because webmaster are doing it without informing users.

Not from the the javascript miner itself. Typically, attackers exploit vulnerabilities introduced by out of date plugins or flaws in the browser itself. Browser based mining does not make you any more or less vulnerable to a virus. However, stay safe, update your plugins and browser!

For the individual end user, no. But, for organizations running larger websites, yes. Browser mining offers very lucrative incentives for unscrupulous agents to try and access websites and inject javascript miners. Organization need to learn to protect themselves: please... http://www.dvwa.co.uk/. There is also an increased incentive for botnets. A controller could have their bots point towards a web page with web miner installed. Botnets aren't specific to browser miners though and likely would not be the first choice to monetize them.

Javascript miners will not harm your computer. They make use of your computer's resources like any other application. When you watch internet videos your system is using its resources to render that video, same with video games, same with installed applications. There is nothing that happens to your computer that is different from any other use. Just like all other programs, a browser based javascript miner will use a small amount of electricity to run this process.

Is possible for an individual to load up a browser based miner and start using their processor to mine cryptocurrencies. However, the amount that you would make is so small that it's not even worth your mind space. If you are determined, you should look into system based miners like Claymore. Browser based miners make a lot of sense for content creators/distributors (webmasters) that have a digital properties they are looking to monetize. Some examples are bloggers, news sites, wiki & how-to's, mobile apps, and more.

Users pay slightly more electricity than they would otherwise. Our initial findings shows the average user consumes $0.03 of additional electricity per hour while running a browser miner. At 2 hours a day, that's 2 bucks a month. Website Owners make small amounts of crypto currency (currently XMR). The average users hashrate is 20 H/s. At the time of writing that provides a profit of $1.50 USD per month. How much money you can make depends on the power of your users computers, and how long they stay on your site

From analytics get the number of monthly users & average session duration in MM:SS format. Apply it to the following formula below will give you a crude calculation Monthly profit = (Monthly Users * ((Avg. Sess. Dur. Minutes/60) + (Avg. Sess. Dur. Seconds/2600)) / 730) * $1.50 Or, instead of multiplying by $1.50 at the end, you can take the number and enter it into a hashrate profitability calculator Example: Monthly Users = 3000 Average Session Duration = 3:30 3000 * ((3/60)+(30/3600)) / 730 3000 * (0.05 + 0.008333) / 730 3000 * 0.0583 / 730 12.152 Multiply by $1.50 to get rough estimate of $18.23 monthly profit Or enter 12.152 into hashrate profitability calculator If you quickly do the math on advertising revenue using numbers comparable to the ones above. Page Views = 7500 Click Through Rate = 0.5% Cost per click = $2.50 7500 * 0.005 * (2.5 * .68 <-- publishers cut) $63.75 While we made a lot of assumptions about the numbers, you can see that a site of comparable size will likely make more money through ad revenue, but browser mining offers an additional 30% to your bottom line.

There are a ton of benefits for creators, users and the general public. For the creator, the methods to make money from websites are generally limited to either pay walls or advertising. We're not knocking them, they are great ways to make money. Browser mining offers a strong addition to these methods that allows user a more direct way to compensate creators. Typically web owners only get compensated through advertising if a user clicks on ads surrounding their content. It's a game of numbers and chance. A small number of users that click on advertising and end up purchasing from the advertiser, pay for the whole show. For on site display banner, it's about 1 in every 200 users. Once again, we're not knocking this, in fact irl I do this for a living. It is a bit of a conflict of interests; creators want to make money by sharing great content, and host ads that have users click away from that content. With browser based mining, every user contributes a tiny amount to financial success or the site. For the user they get access to great content. When websites can monetize time on site, they are encouraged to create more meaningful and valuable content that has the user stay longer. They might also be less inclined to implement paywall, which suck. For the general public we get more hash power for the blockchain, which we like quite a bit. Blockchain technology will arguably be as impactful as the rise of machine learning technology. The more people contributing hash power, the more stable the blockchain.

We're pretty sure Google, Facebook and the rest of the established powers are going to come out swinging against this technology. Pretty easy to predict the future by looking at economic interests and they will likely see it as a threat to their revenue streams. But until then, weeeeeeeeeeee!
