Altcoin exchange deposit activity rose sharply in the two weeks to September 28, but the headline figures need some context. A count-based surge can look like heavy buying at first glance. CryptoQuant reads it more cautiously, as a sign that holders may be preparing to sell.
The seven-day total reached 78,000 deposit transactions on September 28, up about 160% from around 29,800 on September 14. In the same comparison, the number of addresses sending altcoins to exchanges nearly tripled, from roughly 17,600 to 51,600.
The important detail is that these are rolling transaction and address counts, not the dollar value deposited.
The transaction total depends on the source
CryptoQuant’s September 29 weekly report put the seven-day sum at 76,000 transactions and 51,000 depositors.
Neither source read for this report reconciled the difference. The available material also doesn’t establish whether the address figures are unique holders, whether the addresses were deduplicated, or how they were handled across exchanges.
So the direction of the change is clear, but the exact total isn’t. That is worth keeping in view before treating 78,000 as a precise market-wide measure.
More addresses were involved
The wider participation may be the more useful part of the data. CryptoQuant research head Julio Moreno said the increase was broad rather than the work of a few large wallets.
That points away from a simple story about one whale moving coins. It doesn’t tell us which altcoins were involved, which exchanges received them, or whether each address belonged to a different holder. A transaction count measures activity, not the amount sold.
CryptoQuant’s interpretation is that coins moving to exchanges often signal an intent to sell. The report calls a surge in deposits a sign of distribution. That is an interpretation of wallet behaviour, not proof that every transfer became a market sale.
Why CryptoQuant is watching Bitcoin
In CryptoQuant’s report, the altcoin deposit surge appears as a warning for Bitcoin rather than an altcoin-specific story.
Bitcoin holders realized profits on 25,700 BTC on September 22, the largest single day of profit-taking recorded in 2026. Short-term traders’ unrealized profit margin also reached 33%, its highest level since December 2024, The Block reported.
Demand was less convincing beneath those gains. CryptoQuant said apparent Bitcoin spot demand contracted by 170,000 BTC over 30 days. Speculative futures demand growth slowed from 164,000 BTC on September 14 to 16,000 BTC on September 29.
The combination doesn’t settle the market’s next move. CryptoQuant still described the bull market as intact, while warning that stretched profit margins, heavy altcoin inflows and cooling demand could lead to a near-term correction.
No token or exchange breakdown
The public material reviewed doesn’t identify the coins, venues or wallet groups behind the increase. It also provides no altcoin spot prices, ETF flows or stablecoin data. Without those figures, it’s not possible to tie the deposit surge to a particular token or a single market event.
The clean conclusion is narrower, but more defensible: more addresses sent altcoins to exchanges during the period, and more deposit transactions were recorded. Whether that represented broad selling, internal exchange movement or a mix of motives remains unsettled. The available data can’t separate those possibilities.
