Bitcoin is a new currency that was created in 2008 by
an unknown person using the alias Satoshi Nakamoto.
Transactions are made with no middle men – meaning,
no banks! There are no transaction fees and no need to
give your real name. More merchants are beginning to
accept them: You can buy webhosting services, pizza
or even manicures.

Tor or The Onion Router is a network that enables a
user to stay anonymous on the internet and get rid of
any possible surveillance, location tracking, etc. while
using the internet. We can access the Tor network with
the help of a modified Mozilla Firefox ESR web
browser.
Tor or The Onion Router allows a person to browse the
web anonymously by veiling the actual identity of the
user. It protects the user from any traffic analysis and
network spying.
