answers 402

BTC, ETH and USDT dominance as a share of total crypto market cap — the regime filter to check before sizing any altcoin position. Rising BTC dominance means capital rotating to relative safety; rising USDT dominance means capital leaving for stablecoins, a broader risk-off. Falling BTC dominance with rising ETH dominance is the classic rotation signal.
