Wonder what is a satoshi and why do we call it a fraction of Bitcoin?

Sometimes, when the Bitcoin price achieves new highs, some investors hesitate if they should buy this cryptocurrency. Firstly, because they are afraid of the risks connected with the price drop. Secondly, they can simply not have enough money to buy 1 BTC. Finally, they may see no reason for keeping the whole Bitcoin on their account.

Luckily, Bitcoin can be divided into small subunits — up to 8 decimal places. These fractions are named after the creator of Bitcoin - satoshis. It’s basically the only unit that can be recognized by software where Bitcoin nodes run.

The history of Bitcoin

Bitcoin was developed by a group of cryptographers who were trying to create a secure and decentralised network for transferring funds and sharing data. Also, they were looking for a solution for the 'double-spend' problem, when a digital file could be copied and then used repeatedly.

In fact, financial institutions can deal with the issue with the help of a secure database. Banks use special software to track every account's contents. But the computer scientists behind the Bitcoin project wanted a solution that was more akin to physical cash: private, traceable, and not subject to the whims of third parties.

So they launched Bitcoin’s blockchain, a cryptographically secured public ledger that records transactions anonymously.

Originally, Nakamoto's 'white paper' introduced the concept of Bitcoin's value. The article claimed that Bitcoin would provide benefits like eliminating chargebacks for merchants and reducing transaction fees over existing forms of electronic money such as credit cards.

Why is Bitcoin unique?

Bitcoin is the first digital currency that appeared in the world. The coin is proven to be secure as it uses SHA-256 encryption for both its Proof-of-Work (PoW) system and transaction verification. What is more, Bitcoin transactions are technically impossible to copy due to the characteristics of the protocol. The network prevents every participant from carrying out an attack known as a double spend.
