The title of your thread is somehow sketchy, maybe you should change it in to "3 ways on how hacker steal bitcoin",
because your title can be possibly thought as a tutorial to hack a bitcoin.
Just my two cents.

Also if you are exploring the internet, don't click any ads or suspicious link that might bring you to another platform or make you download files from unknown source. Some malware are downloadable and can enter you computer when it disguised as a legit software. So be careful on downloading from any links or websites especially if you have no idea what is it about.

With that, they can track all of you information in your computer to hack your bitcoin so be aware with that.
