Altcoin holders are pushing coins onto centralized exchanges at the fastest pace in roughly a year — and they are doing it in crowds, not in whale-sized blocks. CryptoQuant's Sept. 30 research note puts a number on it, and the number is large enough that the firm has changed the tone of its market read.
What Changed: Altcoin Deposits Hit a 12-Month High
Altcoin exchange deposit transactions — the count of transfers moving non-Bitcoin assets from private wallets onto centralized trading venues — climbed roughly 160% in two weeks, reaching about 78,000 on a seven-day cumulative basis as of Sept. 28 from around 29,800 on Sept. 14 . That is the highest reading since October 2025, and onchain analytics firm CryptoQuant flagged it as rising sell-side pressure on the altcoin market.
Quick Answer: Altcoin deposit transactions to centralized exchanges jumped roughly 160% in two weeks, hitting about 78,000 on Sept. 28, 2026 — the highest since October 2025. Depositing addresses nearly tripled to about 51,600, which CryptoQuant reads as broad-based supply moving toward liquidity rather than a few large wallets repositioning.
The figures carry a reporting discrepancy worth keeping visible. The Block and CoinDesk, citing the same report, put the seven-day count at 76,000 and date the prior peak precisely to Oct. 17, 2025 . FXStreet and Cointelegraph use 78,000. The direction and magnitude agree across every outlet.
| Metric (7-day basis) | Sept. 14, 2026 | Sept. 28, 2026 | Change |
|---|---|---|---|
| Altcoin deposit transactions | ~29,800 | ~78,000 (76,000 per The Block/CoinDesk) | ~+160% |
| Distinct depositing addresses | ~17,600 | ~51,600 (~51,000 per CoinDesk) | ~+193% |
The address count is the detail that matters most here :
- Breadth, not whales. Distinct addresses depositing altcoins nearly tripled over the same fortnight — also a post-October-2025 high.
- Venue split is less firm. Aggregator coverage attributes weekly deposit averages above 22,700 on Binance and above 8,300 on Coinbase, with roughly 32,000 transactions elsewhere . These per-exchange splits did not appear in the tier-one wire reports.
- Positioning, not proof of selling. Coins on an exchange sit next to liquidity; they can also be collateral, rotation, or yield moves.
"When holders move coins to exchanges, they usually intend to sell," — Julio Moreno, Head of Research at CryptoQuant (source: The Block, 2026-09)
Why It Matters: Reading Sell-Side Pressure Against an Intact Bull Market
The deposit spike matters because it lands alongside two other stress readings in the same CryptoQuant report: short-term holders' onchain unrealized profit margin reached 33%, the highest since December 2024, and on Sept. 22 holders realized 25,700 BTC in profit — the largest single-day profit realization of 2026 . Unrealized profit measures paper gains on recently moved coins; when it stretches, the incentive to sell rises.
The second half of the picture is demand. Even as supply moved toward exchanges, buying interest thinned. Spot demand contracted by roughly 170,000 BTC over the trailing 30 days, and futures demand growth fell from 164,000 BTC on Sept. 14 to 16,000 BTC by Sept. 29 . That is a roughly 90% collapse in the rate of new futures demand in a fortnight.
Julio Moreno, Head of Research at CryptoQuant, tied the two sides together directly.
"Without fresh demand, rallies struggle to extend. With spot demand still in contraction and futures growth stalling, near-term upside becomes harder to sustain," — Julio Moreno, Head of Research at CryptoQuant (source: CoinDesk, 2026-09)
His summary judgment was hedged rather than bearish outright: "Still a bull market — but showing signs of fatigue," citing stretched profit margins, record 2026 profit-taking, rising altcoin inflows and cooling demand as warning of a near-term correction . The distinction is operationally important — fatigue inside a trend is a different trade from a cycle top.
What the deposit data does and does not establish:
- Does show: supply repositioned next to exchange liquidity, across a widening set of addresses rather than a few wallets .
- Does not show: executed distribution. Deposits are a positioning signal, not a record of fills.
- Alternative explanations: collateral posting, rotation between assets, and yield or earn products all produce inflows without a sale.
- What resolves it: whether realized profit and spot demand follow the inflows over the coming weeks.
Context explains why holders had gains to bank. Assets outside the top 10 by market cap reached 9% of total crypto market cap on Sept. 27, the highest share since February . Bitcoin dominance has oscillated between 58% and 60.4% since May 27 and sat below 60% .
Aggregator coverage of the report adds scale to that stretch: the Total2 metric, covering all altcoins including Ethereum, absorbed more than $371 billion in inflows since June 2026, a gain of roughly 45% in about four months, with 87% of Binance-listed altcoins above their 200-day moving averages versus 13% in August . Those figures come from secondary coverage, not the tier-one wires, so weight them accordingly.
The structural frame stays constructive. CryptoQuant did not call a top — Moreno noted Bitcoin's close above its 365-day moving average confirmed a new bull market, and the firm's Bitcoin Bull Score Index read 90 of 100 .
What to Watch Next
The next two weeks hinge on four measurable checkpoints, not on narrative. CryptoQuant's own framework gives clear levels and metrics: Bitcoin's position against its long-term moving averages, the Bull Score Index, average deposit size per transaction, and demand flow. Each is observable in the firm's weekly releases, and each can flip the current "fatigued bull market" read in a specific direction.
Start with price structure. CryptoQuant cited three supports: $80,000 (the 365-day moving average), $71,000 (the 200-day moving average) and $67,000 (traders' onchain realized price) . With Bitcoin around $83,300–$85,000 after slipping from a near-$87,400 eight-month high, the $80,000 line is the closest test . A sustained close below it would remove the same signal Moreno used to confirm the bull market.
Then the sentiment gauge. The Bitcoin Bull Score Index sits at 90 of 100, which CryptoQuant describes as extremely bullish . A reading that high has limited room to improve, so the useful signal is deterioration rather than strength. Watch the direction of travel across successive weekly updates, not the absolute number.
The deposit data itself has a second dimension worth tracking:
- Average size per deposit. In July 2026 CryptoQuant argued that a doubling of average Bitcoin deposit size from roughly 1 BTC to 2 BTC was more bearish than raw transaction volume, because it implies deliberate whale and institutional repositioning .
- Address breadth. Depositing addresses tripled to roughly 51,600, so a reversal toward concentration among fewer, larger wallets would change the character of the flow .
- Demand replacement. Futures demand growth fell from 164,000 BTC on Sept. 14 to 16,000 BTC by Sept. 29, with spot demand contracting about 170,000 BTC over 30 days .
That last item is the decisive one. Deposits only become price pressure when there is nothing on the other side to absorb them. As Moreno put it, rallies struggle to extend without fresh demand . If the next weekly release shows spot demand turning back positive while deposit counts cool from the ~78,000 peak, the fatigue reading eases .
The concrete takeaway: treat $80,000 as the line that decides whether this is a pullback inside a bull market or something larger, and treat the demand column in CryptoQuant's next weekly release as the tiebreaker. Supply is positioned near liquidity; it has not yet been sold.
Frequently asked questions
Does the 160% jump in altcoin deposits mean a sell-off already happened?
No. An exchange deposit is a positioning signal, not a completed trade: it shows coins moved next to liquidity, where they can be sold quickly, but the transfer itself is not execution. Deposits can also be collateral, rotation between assets, or yield moves. CryptoQuant's framing of the roughly 160% two-week rise in altcoin deposit transactions is rising sell-side pressure and "signs of fatigue," not a confirmed distribution event . Read it as supply that is now available to sell, and wait for price and demand data to confirm whether it actually is Cointelegraph.
What exactly did CryptoQuant measure?
Two onchain counts, both drawn from tracked centralized exchanges. The first is the seven-day cumulative number of altcoin deposit transactions, which reached roughly 78,000 on Sept. 28, 2026, up from about 29,800 on Sept. 14 . The second is the number of distinct addresses making those deposits, which rose from about 17,600 to roughly 51,600 over the same fortnight — the breadth check that separates a crowd move from a few large wallets . Note that The Block and CoinDesk cite 76,000 transactions and ~51,000 addresses from the same report; the direction and magnitude agree across outlets even where the exact print differs.
Is CryptoQuant calling a top for Bitcoin or crypto broadly?
No. The firm's position is that the bull market remains intact and the risk is a near-term correction inside it. Head of research Julio Moreno noted that Bitcoin's close above its 365-day moving average confirmed a new bull market, and the firm's Bitcoin Bull Score Index stood at 90 out of 100, a reading it describes as extremely bullish . His summary line was deliberately hedged: "Still a bull market — but showing signs of fatigue" . The supports cited alongside that view were $80,000 (365-day MA), $71,000 (200-day MA) and $67,000 (traders' onchain realized price) .
Has this pattern happened before?
Yes, and recently. In early July 2026 CryptoQuant flagged a comparable episode: Bitcoin exchange deposits near 49,000 BTC on June 30 and altcoin deposit transactions approaching 45,000 daily, warning that "historically, surges in altcoin deposit transactions have marked inflection points for crypto prices" . Moreno argued then that the doubling of average deposit size, from roughly 1 BTC to about 2 BTC, carried more weight than raw transaction volume, because larger average tickets point to deliberate repositioning by whales and institutions rather than scattered retail activity . The September 2026 reading differs on that axis: address count tripled, which points to breadth across many holders rather than a concentrated institutional move FXStreet.
