The dominance score of a specific cryptocurrency showcases where that crypto stands, from the perspective of a general crypto market overview - or, in other words, what’s its valuation relative to the rest of the market. Dominance is usually measured with Bitcoin and Ethereum, but the metric can be applied to any other crypto asset, as well. A high BTC dominance, for example, is often seen as a positive thing, since it means that people are investing more into Bitcoin than into other cryptocurrencies.
