Fast answer
Bitcoin-dominance signal checks prove whether market-share movement, breadth, liquidity, and timing were separated.
Before accepting a bitcoin dominance signal, record the dominance source, calculation window, BTC price trend, total crypto market trend, altcoin breadth, stablecoin or ETF context, signal timestamp, trade plan, invalidation, and final result.
If a provider says dominance is rising or falling without showing breadth, price context, and the exact signal time, the rotation claim is weak.
Dominance checks
What to inspect in bitcoin dominance signal records.
Market-share source
The record should name the dominance source and avoid mixing different market-cap methodologies without saying so.
BTC price context
Dominance can rise because BTC is strong, because altcoins are weak, or because both are falling at different speeds.
Altcoin breadth
A real rotation call should show whether broad altcoin performance confirms the dominance move or only a few large coins do.
Trade bridge
The provider should connect dominance context to entry, target, stop, invalidation, updates, and final outcome.
Source context
Bitcoin dominance measures market-share context, not automatic trade direction.
CoinMarketCap describes bitcoin dominance as Bitcoin's market capitalization compared with the total crypto market capitalization. That makes it useful context for market structure, but it does not by itself prove that BTC, ETH, or altcoins should be bought or sold.
Review standard
A reviewable bitcoin dominance signal separates market share from trade execution.
For CSR evidence review, bitcoin dominance records should include data source, dominance level, time window, BTC price, total market cap, altcoin breadth, liquidity context, entry, invalidation, update log, and final status.
