Altcoin trading platforms recorded a 160% surge in top-up transactions over two weeks, with potential selling pressure likely to rise.

CryptoQuant’s latest data shows that the 7-day cumulative number of deposit transactions of altcoins flowing into trading platforms rose to 78,000 on September 28, up roughly 160% from around 29,800 on September 14, marking the highest level since October 2025. During the same period, the number of addresses depositing altcoins to exchanges increased from approximately 17,600 to 51,600, nearly tripling, also hitting a new high in nearly a year. CryptoQuant stated that this round of exchange inflows is widespread, and noted that holders transferring tokens to trading platforms typically signals preparation for selling, so the relevant data may indicate potential selling pressure. Meanwhile, altcoins have recently outperformed Bitcoin. Bitcoin’s market capitalization dominance has fluctuated between 58% and 60.4% since May 27, and remains below 60% as of press time; crypto assets outside the top 10 by market cap accounted for 9% of the total market cap on September 27, the highest level since February this year.
