Bitcoin is a virtual currency that uses Blockchain technology for secure payments and storing money electronically, without requiring a bank or a person’s name. Satoshi Nakamoto created this cryptocurrency back in 2009.

It can be used for booking a hotel or flight, or purchasing products online, as many online stores and companies accept Bitcoin now.
