Altcoin Exchange Deposits Surge 160%, Warns of Potential Sell-Off

According to on-chain data from CryptoQuant, altcoin holders have been moving coins to exchanges at an accelerated pace over the past two weeks. This has resulted in a 160% increase in altcoin deposit transactions and a threefold rise in addresses sending altcoins to exchanges.

The seven-day count of altcoin deposit transactions reached 78,000 on September 28, the highest level since October 2025. The number of addresses sending altcoins to exchanges also surged from around 17,600 to approximately 51,600 over the same period.

CryptoQuant described this buildup as broad-based rather than concentrated among a small group of participants. They noted that 'when holders move coins to exchanges, they usually intend to sell.'

The analytics platform framed the increase in exchange inflow activity as the strongest since Bitcoin's last all-time high, placing near-term selling pressure risk on the table.
