How to block cryptocurrency mining in your Browser
Cryptocurrencies are virtual or digital currencies that are secured by encryption. As we know that the cryptocurrency system is a decentralized system, so no country, organization or authority controls it. In recent years we saw a steep hike in the value of cryptocurrency (not to forget bitcoin value which reached a whopping $19783 in December 2017).
Many websites simply tell you when you visit their website that they will use your CPU power to mine coins till you stay on their site. Some websites also let you choose whether to let them mine coins using your CPU and use their services ad-free or browse/use their services/websites with ads on them. Here you get to choose if you want them to mine or go with ads. This is a legitimate way to earn some money for their business to keep rolling.
In most cases, it is totally harmless but this will affect your computer performance and battery life. It will also hike up your electricity bill marginally (in some cases). It’s a great exchange if you are not a fan of ads. That is why we recommend to block cryptocurrency mining for the websites which don’t disclose what they are up to.
But the real problem comes when websites owners mine on you without your consent and keep using your CPU resources even after you have left their site or closed the browser. They will keep working in background undetected. Some are so advanced that you can’t even detect or know that something is slowing down your computer.
Most users don’t mind websites owners mining coins on their PC till they are on their website but not everyone like it. Is there any way you can be sure that nothing is stealing your power? Of course, there is a way and following it you can easily block such mining in your browser.

How to Detect and block Cryptocurrency mining on your browser
If you suspect that any site is using your PC to mine coins then the very first basic thing you can do to detect is check your task manager or activity monitor which tells you how much resources are being used and by whom. Basically, any website using your PC for mining will hike up the CPU usage. We will use this method to find out the culprit.
Windows user open (Task Manager) – CTRL+ALT+DEL
Mac Users open (Activity Monitor) – Command+Space and search for activity monitor.
Now once you have opened your task manager or activity monitor, go to every site you suspect one by one. After visiting each website check the task manager to see if it hikes up the CPU usage or not and check till your suspect list is empty or you find the culprit.
If you are using chrome browser then you can also check resource usage from the browser itself. Just go to menu (top right 3 dots)>more tools>task manager and this will show window/tab wise CPU usage. This way you can even detect the mining website.
