Satoshi (sat)
A satoshi is the smallest unit of bitcoin — one hundred-millionth of one BTC (0.00000001 BTC). There are 100,000,000 satoshis in every bitcoin, making small everyday amounts practical to price.
If bitcoin trades at $60,000, then $1 buys about 1,667 sats, and 100,000 sats are worth $60.
Named after bitcoin's pseudonymous creator Satoshi Nakamoto, the satoshi exists because one whole bitcoin became too valuable for everyday denominations. Rather than buying "0.00153 BTC", you can think in sats — the way cents relate to dollars, but with eight decimal places instead of two.
Thinking in sats also reframes accumulation: a fixed monthly purchase buys a variable number of sats depending on price, which is exactly what a dollar-cost-averaging strategy tracks.
