#Bitcoin dominance sitting right on a 3 year long support area here.
Bitcoin Dominance is a measure of how much of the total market cap of crypto is comprised of Bitcoin.
The most important thing about Bitcoin Dominance is that it can help you understand if altcoins are in a downtrend or uptrend against BTC.
When BTC Dominance increases, alts on the whole lose BTC value.
So watch closely wether it finds support or not!
