Short answer#

Short answer

Bitcoin dominance and altcoin season context. Learn how Bitcoin dominance is calculated, why indices differ, and why a rising or falling share does not prove an altcoin season or determine market direction.

What to check first

The denominator changes the result#

A dominance calculation depends on which assets are included and how circulating supply and market capitalization are estimated. Excluding or including stablecoins, wrapped assets and illiquid tokens changes the percentage.

Altcoin season is not one standard measure#

Altcoin-season indices can use different token baskets, return windows and thresholds. A label from one methodology may not appear under another, and survivorship can affect historical comparisons.

Market share is not price direction#

Dominance can rise while Bitcoin rises, falls or moves sideways because relative performance matters. Falling dominance does not prove that every altcoin is gaining or that the trend will persist.

Key principles#

Check the universe

Identify which assets, supply figures and market-cap rules are included.

Check the window

Altcoin-season labels depend on the return period, threshold and token basket.

No token selection

MarketPulse does not use dominance to recommend Bitcoin, an altcoin or a portfolio allocation.

FAQ#

How is Bitcoin dominance calculated?

It is generally Bitcoin market capitalization divided by the market capitalization of a defined crypto universe, but inputs and inclusion rules vary.

Does falling Bitcoin dominance prove an altcoin season?

No. The result depends on methodology and relative market moves, and it does not show that all altcoins are rising.

Is dominance a trading signal?

No. It is a descriptive market-share measure and not a buy, sell or allocation instruction.
