Satoshis, or sats, are the smallest unit of bitcoin (BTC), the world-famous peer-to-peer technology operating without any input from banks or government. 100,000,000 satoshis make up one bitcoin. Some people see sats as a useful way of addressing unit bias – where people prefer whole units over a fraction of a unit. As a full bitcoin is now considered too pricey for many retail investors to acquire – so the thinking goes – people may've become less inclined to trade it. Others on the Internet have voiced the opinion that working in sats makes 'bitcoin appear cheap', and will partially obscure the cryptocurrency's massive growth to date. Regardless of who's right, a bitcoin will always be a bitcoin. It'll always be 100 million satoshis too.
