Statistics on Altcoin Market Capitalization Changes Compared to BTC (Updated to the end of May 2026).

1. Basic Parameters
- Total crypto market cap (Total MC): Approximately $2.47T – $2.56T USD (down ~0.8–2.9% in 24h, down ~26–28% compared to 1 year ago).
- #Bitcoin market cap (BTC MC): Approximately $1.46T – $1.50T USD (BTC price ~73,400 USD, sharply down ~42% from the peak ~126,000 USD in October 2025).
- #Altcoin market cap (TOTAL2 – total MC minus native Bitcoin): Approximately $1.0T – $1.08T USD.
- Bitcoin Dominance (#BTC.D): 57.6% – 59.6%
- Stablecoin MC: ~318 billion USD (~12.43% of total MC) — a significant distortion factor.
- Altcoin Season Index (CMC / Blockchaincenter): ~33 (the “#BitcoinSeason”). Ngưỡng #altseason” usually >75).
Quick assessment: Currently, it is a clear #Bitcoin season phase.
2. Analysis
First
#Altseason truly occurs when simultaneously:
- BTC sideways or slowly rising.
- BTC.D drops sharply (usually <55%, ideally <50%).
- Total market cap increases (new capital flows in).
- A strong enough story + #AltSeason Index >75.
Currently, conditions 2 and 4 are not met → no broad #altseason yet.
Second
- ETF & capital allocation: Large capital flows into #BTC (và một phần #ETH) → high structural dominance.
- Macroeconomics and liquidity: 2026 is in a correction phase after the 2025 peak. Recent ETF outflows (billions of USD) exert pressure.
- The story is quite fragmented: 2025 features memecoins, AI, RWA but lacks the strong cohesion seen in DeFi 2020-2021.
- Stablecoin: ~12% of total MC is stablecoins → “pumping” the index but not true altcoin investment.
3. Conclusion
This cycle is distinctly different from 2017 and 2021. Alts are in a “inefficient productivity” phase lasting due to capital flows favoring native Bitcoin and lacking a strong connecting story. The volatility of #altcoin so với #BTC market cap is currently negative and will continue until BTC.D truly #breaks down + new capital flows back into the market.
Wishing you peace and happiness.
Wishing you joy and fulfillment.
