Stacking sats means accumulating small amounts of bitcoin over time.
A sat (short for satoshi) is the smallest unit of bitcoin - one hundred millionth of a bitcoin.
People use the phrase when they’re:
- buying small amounts of bitcoin on a regular schedule,
- earning bitcoin and holding onto it,
- focusing on long-term accumulation rather than short-term trading.
It’s a common shorthand among Bitcoiners for a slow, consistent approach to building a bitcoin balance.
