No. Despite what lots of media outlets are saying, browser based mineing 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.
Is possible for an individual to load up a browser based miner and start using their processor to mine crypto currencies. 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 (web masters) 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 comptuers, 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 = (Montly 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
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
pay wall, 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 block chain.
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!
Of course! there are several ways to stop these scripts from runing in your browser. It is our intention that webmasters would
allow their users the choice, and we're building functionality to make it really easy for both the webmaster to offer and the
user to control. Newer version of browsers are offering anti mining you can toggle on and you can also use adblocking
plugins (but we wont go as far as to tell you which ones) which support browser blocking.
The short answer is that transparency is always the best policy and we hope browser based mining catches on in a big way.
It won't if people think this is something that is being forced on them. We want people to understand that this is an incredibly
efficient way to support the content they love!
