BITCOIN DOMINANCE

BTC dominance, BTC.D, BTC dom, or Bitcoin dominance is a metric that measures the market capitalization of Bitcoin and compares it to market capitalization of all other cryptocurrencies. This ratio is very useful in trading because when Bitcoin is growing and BTC.D is on the rise, altcoins usually retrace and bleed whilst when Bitcoin is ranging and BTC.D is going down, altcoins usually run.
