The Rotation Sequence
Crypto market cycles follow a rough sequence that has repeated, with variations, across the 2017, 2020-2021, and subsequent cycles. Bitcoin leads. Capital flows into BTC first as the highest-liquidity, lowest-risk entry point for new money. As BTC stabilizes after its initial move, profits rotate into large-cap altcoins (Ethereum, Solana, and other established Layer 1 protocols). Then mid-caps. Then small-caps and meme tokens.
During 2021's rotation phase, large-cap altcoins delivered 174% returns while Bitcoin managed only 2% over the same period. The sequence is not random. New capital enters through the most familiar, most liquid asset. As it appreciates, early investors take profits and deploy further out on the risk curve, seeking higher returns on assets that have not moved as much.
Measuring Rotation Quantitatively
Bitcoin dominance (BTC's share of total crypto market capitalization) is the simplest rotation metric. When BTC dominance rises, capital is flowing toward Bitcoin relative to altcoins. When it falls, capital is rotating into alts. This single metric, combined with whether total market cap is rising or falling, gives you four regimes.
Rising total market cap plus falling BTC dominance is the classic "alt season" setup. The total pie is growing and alts are capturing a larger share. Rising total cap plus rising BTC dominance means new money is coming in but concentrating in Bitcoin. Falling total cap plus rising BTC dominance is a flight to quality within crypto. Falling total cap plus falling BTC dominance is rare and usually indicates extreme distress.
Bitcoin dominance has ranged from peaks above 70% (early cycle) to troughs near 38-40% during late-cycle altseason peaks in 2018 and 2021.
Sector-Level Analysis
Within the altcoin universe, capital rotates between sectors in patterns that mirror equity market sector rotation. DeFi protocols, Layer 1 blockchains, Layer 2 scaling solutions, gaming tokens, AI-related tokens, and meme tokens each have periods of relative outperformance and underperformance.
The rotation between sectors is driven by narrative shifts. When a new technological development captures market attention, capital flows toward tokens in that sector. When the narrative fades or expectations are not met, capital rotates out. Tracking which sectors are gaining relative volume and market cap share tells you where current narrative momentum is concentrated.
The Accumulation-Markup-Distribution-Markdown Framework
Individual altcoins and sectors cycle through four phases that map to the Wyckoff model. Accumulation is the quiet period after a decline, where informed buyers start building positions at depressed prices. Volume is low but holding patterns shift from weak hands to strong hands. Markup is the trending phase where price rises on increasing volume. Distribution is where early buyers sell to late arrivals, price stalls, and volume becomes choppy. Markdown is the decline that follows.
Identifying the phase helps calibrate expectations. The highest-reward entries are during accumulation, but they require patience and conviction. Markup entries have more confirmation but lower potential returns. Distribution and markdown are where capital destruction occurs.
Composite Scoring for Sector Health
Rather than relying on any single metric, a composite score aggregating volume trends, relative performance, momentum indicators, and on-chain activity (active addresses, transaction counts, developer commits) across each sector gives you a stronger picture. A sector showing improving fundamentals, increasing development activity, and rising relative price performance is in a stronger position than one where only price is moving.
The practical value is in asset allocation. If your composite scorecard shows DeFi in accumulation while meme tokens are in distribution, that informs how much of your active portfolio you allocate to each sector. Not as a binary signal, but as a probabilistic input that tilts your portfolio toward where the cycle is heading rather than where it has been.
