Explain how BTC, ETH, and alt dominance ratios shift across a cycle and what each shift implies.
Three ratios, one rotation
BTC dominance tells you Bitcoin's slice. But on most charting platforms you can also pull up ETH dominance — Ethereum's slice — and OTHERS dominance, which is the share of the crypto market that is neither BTC nor ETH. Looking at all three together gives you a more complete map of where capital is in the cycle than BTC.D alone can.
The historical rhythm across past cycles tends to go in this order. Early cycle, BTC leads. Capital coming back into crypto trusts Bitcoin first. BTC.D rises while ETH.D and OTHERS.D drift sideways or down. Mid cycle, ETH starts to catch up. Smart-contract activity picks up, ETH outperforms BTC, and ETH.D rises. Late cycle, alts take the relay. OTHERS.D begins to climb fast as narrative-driven coins absorb the last waves of attention and liquidity. Then the cycle peaks, and the same ratios reverse — usually with OTHERS giving back the most, ETH next, and BTC holding up best.
How do you use this practically? Three ways. First, knowing roughly where you are in the rotation shapes what you focus on. If ETH.D is rising sharply while BTC.D is flat, the middle-cycle frame is in play and ETH-ecosystem exposure makes more sense than chasing micro-caps. Second, when OTHERS.D starts climbing aggressively, you know late-cycle dynamics are activating — that is when risk management has to tighten, not loosen. Third, the reversal in OTHERS.D often comes first when a cycle is ending. Watching it roll over before BTC does can save you from giving back gains.
Recap: BTC.D, ETH.D, and OTHERS.D together describe rotation across the cycle. BTC leads, ETH catches up, alts run last, and then the chain reverses. Use the map to focus your exposure on what the cycle is actually offering, not what your group chat thinks should be hot. One last note worth carrying — even in a clean rotation, the moves do not arrive on a fixed schedule. Some cycles compress all three phases into a few months. Others stretch over more than a year. The order of the relay tends to hold; the timing rarely does. So track the ratios, but do not bet the account on a calendar prediction. Track the ratios, anchor on what BTC.D and total market cap are doing together, and let the dominance picture confirm or contradict what you are seeing in individual baskets.
