Satoshi
Smallest unit of Bitcoin — 1 satoshi = 0.00000001 BTC.
A satoshi is the smallest indivisible unit of Bitcoin, named after Bitcoin's pseudonymous creator — Satoshi Nakamoto.
Unit system:
•1 Bitcoin = 100,000,000 satoshis
•1 satoshi = 0.00000001 BTC
•1,000 satoshi = 0.00001 BTC
•100,000 satoshi = 0.001 BTC
Why it matters:
•Enables microtransactions — Lightning Network uses satoshis
•Psychological accessibility — "I can't afford BTC" → "I can afford satoshis"
•21 trillion satoshis total (21M BTC × 100M satoshi)
Satoshi accumulation:
•"Stack sats" — popular crypto phrase for regularly buying small BTC amounts
•Sats/dollar — alternative way of viewing BTC price
•If BTC = $100,000: $1 = 1,000 satoshis
Satoshi Nakamoto:
•Anonymous creator of Bitcoin (or group)
•Owns ~1 million BTC (Satoshi coins) — not moved since 2009
•Identity remains unknown, the only adequate mystery of crypto history
Msats (millisatoshi): used in Lightning Network for even smaller transactions.
