How this service works
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.
Output
Returns BTC dominance, ETH dominance, and USDT dominance as percentages of total crypto market capitalization, along with contextual signals indicating whether the market is in a risk-on, risk-off, or rotation regime — helping the agent decide whether conditions are favorable for altcoin exposure.
Example use cases
Altcoin position sizing regime check
“Before I add to my altcoin bag, can you pull the current BTC and USDT dominance figures and tell me whether the market is in a risk-on or risk-off regime?”
Detecting BTC-to-altcoin rotation
“Is BTC dominance falling while ETH dominance is rising right now? I want to know if we're seeing the classic rotation signal into altcoins.”
Stablecoin flight risk monitoring
“How high is USDT dominance right now? I want to see if capital is fleeing into stablecoins before I make any moves in the altcoin market.”
