Though late, the alt season has arrived: Four signals reveal that early rotation has begun.

Author: BitMEX

It’s not a meme, it’s the data speaking. We judge that an early round of copycat season is unfolding, and the reason is very simple:

• Market Structure: TOTAL3 (total market cap of altcoins excluding BTC/ETH) stabilizes relative to the two major mainstream coins; even without a volume breakout from BTC/ETH, market breadth is also expanding.
• Leading direction: SOL/ETH is rising, funding rate is moderate, not many liquidations – real buying, not short squeezing.
• Catalytic factors: The U.S. government is promoting blockchain applications, with the Department of Commerce putting official data such as GDP and PCE on the chain (via Chainlink/Pyth), and the platform token undergoing periodic revaluation, bringing “off-market” funds back on-market.
• ETF Funds: ETFs are still experiencing net inflows but are clearly cooling down; the market value/net asset value ratio (m/NAV) of ETH-related DAT (coin stocks) is relatively low → the attractiveness of issuance declines, which may leave more space for altcoins.

Signal 1 | Market Structure and TOTAL3’s Resilience

The market trend over the past 5 days resembles the beginning of an altcoin season rather than a rotation of “only rising mainstream”. TOTAL3 did not make new lows while BTC and ETH were fluctuating; the derivatives side remains orderly: funding rates are close to neutral, and passive liquidations are limited—pointing to genuine demand driven by spot trading. For traders, the focus is clear: without waiting for BTC/ETH to make new highs, breadth can also expand; selecting altcoins in pair trading offers better cost performance.

Signal 2 | SOL outperformed ETH, starting to rotate

The upward movement of SOL/ETH, alongside a stable funding rate and no obvious signs of short squeezing, indicates genuine buying demand from active allocation. Historically, this often precedes a rotation of pairs in high liquidity mid-cap and functional tracks; it also provides a lower β expression: going long on SOL / going short on ETH.

Signal 3 | Mainstream coins are “stable, but not trending”

The fundamentals of mainstream coins remain positive, but the marginal momentum of ETH and BTC is declining: there’s support during pullbacks, but a lack of follow-through on upward movements makes it difficult to push to new highs.

Taking Ethereum coin stocks as an example, the m/NAV is mostly between 1.0–1.1×, underperforming the spot ETH, making it difficult to sustain the chain of “additional issuance + passive spot buying.” Our judgment is: mainstream bottom-fishing is strong, while chasing highs is weak, and marginal risks should sink to altcoins with event-driven catalysts.

Signal 4 | Deployable blockchain applications in advancement

Both policy and infrastructure have strong catalysts: The U.S. Department of Commerce announced that official series such as real GDP, PCE, etc., will be put on-chain (via Chainlink, Pyth, covering Arbitrum, Avalanche, Base, etc.), providing authoritative and machine-readable data that opens new scenarios for data-driven DeFi, tokenized risk management, and event markets.

At the same time, blockchain-based applications have also gained recognition and adoption from mainstream institutions, with Numerai (an AI-driven hedge fund incentivized by $NMR) receiving a $500 million strategy capacity commitment from JPMorgan Asset Management.

Platform tokens are strengthening in phases: OKB is boosted by adjustments to its token model, while CRO is gaining attention due to news related to investments from the Trump family fund. These developments do not rely on BTC/ETH hitting new highs — this is a typical characteristic of the early altcoin season.

Conclusion | Trading Framework

Current situation: mainstream orderly, ETF net inflow cooling, DAT premium is thin, hard catalysts are bringing funds downstream.

Continue to prioritize pairing and news in strategy:

• Core Position: Long SOL / Short ETH; Pay attention to the rise of new coins.
• Satellite Positioning: Anchored by event catalysts, gradually allocate news-driven altcoins during pullbacks; until capital flows, funding rates, or key proxy indicators clearly signal a style switch.
