What is Satoshi?
The smallest unit of Bitcoin — one hundred-millionth of a BTC — named for Bitcoin's pseudonymous creator. Prices in sats make small amounts legible.
A satoshi — "sat" — is Bitcoin's smallest unit: one hundred-millionth of a coin, named for its pseudonymous creator Satoshi Nakamoto. At any Bitcoin price, sats make small amounts legible: rather than owning 0.00043 BTC, you own 43,000 sats — the same fact, kinder to human brains.
Sats also dissolve the most common beginner objection — "Bitcoin is too expensive for me" — which quietly assumes you must buy a whole one. Bitcoin is divisible to eight decimal places; every budget buys sats. The related trap is unit bias: coins priced in fractions of a cent feel cheaper than sats do, while being nothing of the sort.

FAQ
Who is Satoshi Nakamoto?
The pseudonymous creator of Bitcoin, active from 2008 until vanishing in 2011, identity never established. The disappearance matters more than the mystery: Bitcoin has no founder to subpoena, lobby or arrest — by design or by luck.
How many sats are in one Bitcoin?
100,000,000 — eight decimal places. Whatever Bitcoin's price, dividing by a hundred million is what makes "stacking sats" possible on any budget.
