Analysis Workflow

Step 1 — Market Cap & Dominance Analysis

From the markets data, compute:

Total Crypto Market Cap:

Total_MCap = sum(market_cap for all coins in response)

Bitcoin Dominance:

BTC_Dominance = BTC_market_cap / Total_market_cap × 100

Ethereum Dominance:

ETH_Dominance = ETH_market_cap / Total_market_cap × 100

Altcoin Dominance = 100 - BTC_Dominance - ETH_Dominance

Dominance Signal:

Step 2 — Bitcoin Cycle Analysis

Key Bitcoin Halving Cycle Facts:

• Halving events approximately every 4 years (~210,000 blocks)
• Last halving: April 2024
• Historical pattern: Strongest appreciation typically 12–18 months post-halving
• Cycle phases: Accumulation → Early Bull → Full Bull → Peak → Distribution → Bear → Capitulation → Recovery

Current Cycle Position: Based on time since last halving (April 19, 2024), estimate cycle phase:

• 0–6 months post-halving: Accumulation / Early Bull
• 6–18 months post-halving: Bull market expansion
• 18–30 months post-halving: Late bull, increasing volatility
• 30–48 months post-halving: Distribution / Bear market

ATH Distance:

BTC_ATH_Distance = (BTC_current_price / BTC_ath) - 1 (as %)

• Within 20% of ATH: Price discovery zone / near peak
• 20–60% below ATH: Bull market territory

• 60% below ATH: Capitulation / deep bear

Step 3 — Volatility & Risk Assessment

30-Day Rolling Volatility (Annualized): From historical price data:

daily_returns = price.pct_change()
vol_30d_annualized = daily_returns.rolling(30).std() × sqrt(365) × 100

Crypto Volatility Regimes:

• < 40% annualized vol: Low volatility — consolidation or gradual bull
• 40–80%: Normal crypto volatility

• 80%: High volatility — extreme moves likely in both directions

• 120%: Crisis / capitulation volatility

Drawdown from ATH:

Max drawdown from ATH = (current_price - ath) / ath × 100

Sharp Decline Detector (last 7 days):

• If 7-day return < -20%: Cascade selloff / forced liquidation — potential bounce setup
• If 7-day return > +30%: Parabolic move — profit-taking warning

Step 4 — Altcoin Season Index

Estimate altcoin season based on dominance ratios and altcoin vs. BTC performance:

Altcoin Season Signal:

• If > 75% of top 50 altcoins outperformed BTC in last 30 days: Altcoin Season 🔥
• If 25–75% outperformed: Ambiguous / Mixed market
• If < 25% outperformed BTC: Bitcoin Season — capital concentrated in BTC

From the markets data, compute how many of the top 20 coins beat BTC's 7-day return:

beating_btc = count(coin for coin in top_20 if coin.7d_return > BTC.7d_return)
ratio = beating_btc / 20

• 0.75: Altcoin season

• 0.25–0.75: Mixed
• < 0.25: Bitcoin season

Step 5 — Layer-1 Competition Analysis

For major L1 blockchains (ETH, SOL, ADA, AVAX), compute relative performance vs. BTC:

Relative_Return = coin_7d_return - BTC_7d_return

Identify which L1s are gaining / losing market share.

Step 6 — Macro Correlation Assessment

Crypto increasingly correlates with risk assets (Nasdaq) during certain regimes:

• If broad equity market is in risk-off (use /v1/market/summary if available): Crypto headwind
• If monetary policy is tightening (high real rates): Suppresses speculative assets including crypto
• BTC as "digital gold" narrative: Check if gold is also rallying (use /v1/free/commodity/price/gold)

Note the correlation context without making definitive claims.

Step 7 — Sentiment Proxy

Use market data as a sentiment proxy (actual Fear & Greed Index data unavailable):

Sentiment Estimation from Data:

• Extreme Greed: BTC within 10% of ATH + altcoins > BTC + high volume
• Greed: BTC 10–25% from ATH + broad crypto market rising
• Neutral: Mixed performance + normal volume
• Fear: BTC 25–50% from ATH + altcoins underperforming + declining volume
• Extreme Fear: BTC > 50% from ATH + most altcoins at deep losses + low volume / capitulation

Limitations

• Crypto markets trade 24/7; data may be minutes old but not real-time tick data.
• Regulatory risks (SEC actions, country bans) are not captured in price data alone.
• Halving cycle analysis is based on historical patterns — the 4th+ cycles may behave differently.
• DeFi-specific metrics (TVL, protocol revenue, DEX volume) are outside this skill's scope.
• Crypto is a highly speculative asset class; treat all analysis as research, not investment advice.
