Altseason Alert: CryptoQuant Analyst Reveals Critical Accumulation Signal—Is This the Rally Trigger?

Whales are loading up—and history suggests altcoins might be primed for liftoff.

CryptoQuant's latest on-chain data shows a stealth accumulation pattern eerily similar to pre-bull market conditions in 2020 and 2023. When institutions and OTC desks start hoarding mid-caps while retail sleeps, fireworks usually follow.

Key signals flashing:

- Stablecoin reserves hitting 18-month highs (because nothing says 'confidence' like parking cash in digital IOUs)

- Exchange outflows spiking for ETH, SOL, and DOT

- Futures open interest oddly flat despite spot buying

Market makers appear to be building inventory the old-fashioned way: buying the damn dip. Meanwhile, your average trader remains distracted by Bitcoin's sideways grind and the latest celebrity meme coin rug pull.

Will this be the cycle where 'wait for confirmation' traders miss the first 200% move? The charts are whispering 'yes'—but since when does Wall Street listen to whispers?

CryptoQuant analyst Axel Adler Jr. has spotted a potential early sign of a new altcoin wave. In a recent post on X, he revealed that altcoin exchange inflows have dropped sharply – something that’s often followed by strong market rallies. Could this be the start of the next “altseason”?

As of June 27, the average monthly altcoin exchange FLOW stands at $1.6B, below the annual average of $2.5B. This moderate flow suggests asset consolidation and growing accumulation potential ahead of the next altseason wave.

Let’s break down what’s happening.

Exchange Inflows Plummet: A Bullish Omen?

Adler Jr. noted that the usual monthly inflow of altcoin exchanges has declined by 36%, falling from an annual average of $2.5 billion to only $1.6 billion as of June 27, 2025. This $900 million decline suggests reduced selling pressure, as investors are holding onto their assets rather than liquidating.

Historically, these small inflows have anticipated significant altcoin price rises, as seen during the jumps from August to September 2024 and throughout the second half of 2023.

Adler Jr. noted that in all instances, minimal trading activity preceded significant altcoin price increases, fostering Optimism among traders.

Why Lower Inflows Can Be Bullish for Altcoins

So, why does this matter? When less capital is moving into crypto exchanges, it usually means there’s less selling happening. Instead, investors might be accumulating, waiting for the next move up.

CryptoQuant’s data shows that when inflows fall below $1.6 billion, it often sets the stage for a strong altcoin rally. It signals a shift – away from short-term speculation and toward long-term holding. Sometimes, capital temporarily moves into Bitcoin first, before flowing back into altcoins with more strength.

This pattern often builds up momentum. And when that momentum swings back to altcoins, prices can surge quickly.

A Shift Is Happening – Is Altseason Next?

Right now, the market seems to be in a transition phase. The drop in exchange inflows is a classic sign of quiet accumulation, which often comes before a rally. If this pattern holds, it could align with a broader market recovery and renewed risk appetite.

So the big question: is the next altcoin rally around the corner?
