Bitcoin is a decentralized cryptocurrency that uses peer-to-peer technology for instant payments between people or businesses.
It's like an online version of cash. You can use it to buy products and services, but not many shops accept it yet and some countries have banned it altogether.
Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computer.
There are many other similar cryptocurrencies like Bitcoin, but Bitcoin is the most expensive of them all.
The price for a single Bitcoin was $32203.64 on January 01, 2021.
