As of September 29, 2026, Bitcoin dominance is around 57â59%, depending on the data provider. CoinGecko currently shows about 57.1%, while CoinMarketCap is around 58.6%.
đ What that means for the market
BTC dominance = Bitcoinâs share of the total crypto market capitalization.
Dominance rising: capital is relatively more concentrated in BTC â altcoins can struggle against BTC.
Dominance falling: capital is relatively shifting toward ETH and other altcoins â usually a more favorable environment for altcoins.
BTC rising + dominance falling: often indicates a broad market rally with stronger altcoin participation.
BTC falling + dominance rising: can indicate investors are moving toward BTC relative to riskier altcoins.
Right now, the interesting part is that dominance has been below 60% and trending somewhat lower, while recent data shows increasing altcoin participation. CoinMarketCapâs Altcoin Season Index is around 63/100, and Glassnode reported that spot trading volume in altcoins has risen to nearly four times Bitcoinâs volume.
đ For ETH and altcoins
For the type of ETH/altcoin setups weâve been watching, Iâd watch BTC dominance + BTC price together, rather than dominance alone:
BTC stable/up + BTC.D falling â đą stronger setup for altcoins
BTC stable + BTC.D rising â đĄ BTC taking relative strength
BTC falling + BTC.D rising â đŽ potentially difficult environment for altcoins
So, the current ~57â59% dominance level is worth watching closely, especially if it continues declining while BTC remains stable. That combination would indicate increasing relative participation outside Bitcoin.
