The smallest unit of Bitcoin is called a *"satoshi"* — named after *Satoshi Nakamoto*, Bitcoin's creator.

### *Quick breakdown:*
1 *$BTC * = *100,000,000 satoshis*

So:
`1 satoshi = 0.00001 BTC`

$BTC can be divided down to 8 decimal places so you can send tiny amounts.
With BTC at ∼$77,670 today:
`1 satoshi ≈ $0.00078` — less than 1 Pakistani paisa.

People often just say "sats" for short. Like "I bought 50,000 sats" instead of "0.0005 $BTC ".

Want me to explain how fees and lightning payments use sats?
