Dominance divides a single asset's market cap by the market cap of all cryptocurrencies. Bitcoin dominance is the figure most often quoted, and traders read it as a rotation signal: when it rises, capital is concentrating in Bitcoin; when it falls, money is spreading into smaller assets.
The measure has a known flaw. The denominator grows every time a new token is listed, so dominance can drift downward simply because the market is being counted more thoroughly, not because anyone sold. Stablecoins are included in most calculations too, which means a flight into cash shows up as falling dominance for every risk asset at once.
What does falling Bitcoin dominance mean?
Usually that other assets are outperforming Bitcoin, which traders associate with a broad rally in smaller coins. It can also reflect new tokens entering the total, so it is read alongside absolute market caps rather than on its own.
