Altcoin (cryptocurrencies other than Bitcoin) deposits to exchanges climbed sharply, with seven-day cumulative deposit transactions reaching 78,000 on Sept. 28, up about 160% from approximately 29,800 on Sept. 14. The level was the highest since October 2025. The number of addresses depositing altcoins also rose from about 17,600 to 51,600, nearly tripling and reaching a new one-year high. Transfers to exchanges often indicate that holders are preparing to sell, potentially pointing to increased selling pressure. At the same time, altcoins have recently outperformed Bitcoin. Bitcoin's market-cap share has fluctuated between 58% and 60.4% since May 27 and remains below 60%. Crypto assets ranked outside the top 10 by market capitalization represented 9% of the total market on Sept. 27, the highest level since February this year.
