- •CryptoQuant noted that coins moved onto exchanges are usually intended for sale, making deposit counts a barometer of how much supply could reach the market on short notice.
- •The jump in deposit activity coincided with Bitcoin briefly surpassing $87,000 last week for the first time since January before pulling back.
- •Glassnode's Altcoin Cycle Signal metric flipped in favor of altcoins last week, and crypto assets outside the top 10 by market capitalization reached a 9% share of the total on Sept. 27, their highest since February.
The number of altcoin deposits flowing into cryptocurrency exchanges has climbed to its highest transaction count since October 2025, according to onchain analytics platform CryptoQuant, which cautioned that holders may be preparing to sell.
Deposit activity hits highest levels since October 2025
In its latest weekly report, released on Tuesday, CryptoQuant flagged a sharp surge in exchange deposits involving altcoins. The seven-day count of altcoin deposit transactions across exchanges tracked by the platform reached 78,000 on Sept. 28 — up roughly 160% from around 29,800 on Sept. 14, and the highest reading since October 2025.
“Altcoin exchange inflows have exploded to their highest levels since Bitcoin’s last all high,” CryptoQuant noted.
Address activity followed a similar trajectory. Between Sept. 14 and Sept. 28, the number of addresses sending altcoins to exchanges nearly tripled, from around 17,600 to about 51,600. The firm said the address count also reached its highest level since October 2025 and described the rise in inflows as broad-based.
“When holders move coins to exchanges, they usually intend to sell,” CryptoQuant added. Inflow gauges carry weight among onchain analysts because coins moved onto trading platforms sit in accounts where they can be traded on short notice, making deposit counts a barometer of how much supply could reach the market quickly. CryptoQuant publishes the figures on a weekly cycle, so upcoming reports will show whether deposit and address counts hold near current levels or fall back toward the mid-September baseline.
The surge in deposit activity comes as Bitcoin (BTC) has pulled back after briefly topping $87,000 last week for the first time since January. As Cointelegraph reported, shifts in exchange order-book liquidity, as well as long-term holder supply, have been cited as potential obstacles to further short-term gains.
Smaller altcoins’ market share hits highest level since February
The increase in exchange deposits follows recent signs of altcoin outperformance against Bitcoin. Last week, Glassnode’s dedicated Altcoin Cycle Signal metric flipped in favor of altcoins over Bitcoin. The metric draws on price data for the 250 largest altcoins by market capitalization, excluding stablecoins, and is designed to flag the kind of broad rotation market commentators refer to as an altseason — an extended stretch in which altcoins collectively gain on Bitcoin.
Bitcoin’s share of total crypto market capitalization, meanwhile, remained below 60%. According to TradingView data, Bitcoin dominance has held within a band between 58% and 60.4% since May 27, a benchmark analysts use to gauge whether market value is concentrated in Bitcoin or spread across smaller assets.
Rotation toward smaller assets is also visible in market breadth: crypto assets outside the top 10 by market capitalization accounted for 9% of the total on Sept. 27, their highest share since February.
