Bitcoin is a cryptocurrency, a new kind of money, and an innovative payment network. It was invented in 2008 by Satoshi Nakamoto (an unknown person or group of people). Bitcoin uses peer-to-peer technology to operate with no central authority or banks, and it is the first decentralized currency based on blockchain technology.

There are no physical bitcoins. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin. Bitcoins are created as a reward for a process known as mining.

Bitcoin got very popular and has triggered the launch of hundreds of other cryptocurrencies known as altcoins.

Bitcoin is often referred to as digital gold. It’s increasingly attracting investors’ interest because it is the most profitable financial asset in the last 10 years.

How does Bitcoin work


“What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party,”

– Satoshi Nakamoto (Bitcoin Whitepaper)

Bitcoin price

Bitcoin broke its all-time-high in December 2020 when reached above 20 thousand dollars. In early 2021 it creates a new all-time-high with 40 thousand dollars. Not only retail investors helped the increase of the price but the institution as well.
