BTCDOM stands for Bitcoin Dominance.

It is a metric that shows the percentage of the total cryptocurrency market capitalization that is made up of Bitcoin. It's calculated using the formula:

BTCDOM = (Bitcoin Market Cap / Total Crypto Market Cap) × 100

Why it matters:

High BTCDOM (e.g., above 50%) means Bitcoin is relatively strong compared to altcoins.

Low BTCDOM (e.g., below 40%) may indicate that altcoins are gaining more market share—often referred to as an altcoin season.
