Tor allows you to anonymity online. It protects your privacy and defend yourself against network surveillance and traffic analysis.
The setup of Tor is very complicated and sometimes you will fail to make it to work. The most easy way is to download Tor Browser. However, it has some limitations and the main problem is that it is for web browsing only.
The drawback of using Tor is the speed. It is quite slow as the traffic passes a lot of nodes in order to hide your IP address and traffic. Your IP will be changed every 10 minutes. The IP is not belonged to your home country.
