Satoshi is the smallest unit of Bitcoin. 1 Satoshi = 0.00000001 Bitcoin. It’s like a penny in USD. Since Bitcoin is superior to fiat currency, its divisibility is much greater, whereas 1 dollar can be divided into 100 cents. 1 Bitcoin can be divided into 100 million coins.

So what do we call this 100 millionth of Bitcoin? The individual unit that makes up a Bitcoin? A Bitcoin is divided into a unit of cryptocurrency known as Satoshis. Each Bitcoin is divisible up to eight decimal places

The satoshi is named after the anonymous “founder” of Bitcoin, Satoshi Nakamoto. Satoshis are also referred to as “sats” in everyday cryptocurrency conversations, as well as an easier way to price goods and services, especially on Layer 2 solutions like the Lightning Network.
