This question already has an answer here:
There's still a way to be 100% anonymous on internet using a computer? I know that using a prepaid SIM card you can surf 100% anonymously, as far as your phone hasn't been bought with a credit card that contains your information.
But..what about using a laptop or a desktop computer?
What do you guys think about Whonix project? Can I be 100% anonymous using it?
