Altcoin market capitalization has increased by more than $371 billion since June 2026, rising about 45% as capital moved beyond Bitcoin into a wider range of tokens. TOTAL2, which includes Ethereum but excludes Bitcoin, stood near $1.17 trillion in TradingView data cited previously. Market participation has broadened, with about 87% of Binance-listed assets above their 200-day moving averages and only 13.6% below them, a marked improvement from a year earlier. The advance now faces a liquidity test after roughly 70,000 altcoin deposits reached exchanges on Sept. 25, the highest total since Oct. 17, 2025, with Binance accounting for much of the flow and Coinbase, Bybit and OKX also recording inflows. Stablecoin supply remains near $305 billion, indicating limited fresh capital, while faster growth in leveraged open interest than spot activity could make the rally more vulnerable if positioning unwinds.
