A massive flow of crypto assets is flooding exchanges. A report from CryptoQuant reveals that the number of altcoin deposit transactions across exchanges surpassed 78,000 over a seven-day period as of September 28. This marks a 160% surge compared to September 14, when transactions stood at just 29,800.
The deposit surge involves a growing number of market participants. CryptoQuant data shows that the number of unique addresses sending altcoins to exchanges has nearly tripled, jumping from just 17,600 addresses in the middle of the month to 51,600 addresses over the same period. This rise in deposit activity is also broad-based, indicating that inflows are coming from a wide range of altcoins rather than being driven by a single project.
The current intensity of altcoin transfers to exchanges matches records set in October 2025. That period coincided with Bitcoin’s rally as it broke its latest all-time high.
Sell Signal Behind Deposit Surge
The heavy influx of altcoin supply entering exchanges has immediately triggered warnings from analysts. Moving crypto assets from private wallets to exchanges follows a clear historical pattern and rarely signals routine accumulation.
“When holders move coins to exchanges, it usually signals an intent to sell,” a CryptoQuant analyst warned. They emphasized that altcoin inflows to exchanges are surging to levels unseen since Bitcoin reached its peak price.
This threat of mass selling pressure comes just as altcoins began showing signs of resilience against Bitcoin. Last week, Glassnode’s Altcoin Cycle Signal indicator released data favoring altcoin performance over Bitcoin.
The improving performance of altcoins pushed Bitcoin dominance below the 60% mark. Meanwhile, crypto assets outside the top 10 managed to capture a 9% share of the total crypto market cap on September 27, marking the highest market share for mid-cap altcoins since last February.
Pullback Amid Price Downtrend
This wave of altcoin exchange transfers comes alongside a pullback in Bitcoin. The largest cryptocurrency retreated after briefly climbing above $87,000 in trading last week, a level not seen since January.
Markets are now confronting an overhang of supply waiting on exchanges. The combination of stalled momentum in Bitcoin and tens of thousands of addresses depositing their altcoins means buyers face an uphill battle absorbing supply to prevent prices from sliding further.
