Altcoin market capitalization has grown over $371 billion since June, a 45% rise, as capital broadens beyond Bitcoin into a wider range of tokens. A spike in exchange deposits and stagnant stablecoin supply, though, point to thinning liquidity behind the rally.
Since June, Total2 has absorbed over $371 billion. That marks a 45% increase in altcoin market value as capital rotates beyond Bitcoin into a wider range of tokens.
The rotation is spreading across Binance-listed assets, where only 13.6% currently trade below their 200-day moving average. By contrast, 87% sit above it, a share significantly higher than a year earlier.
That broader participation points to gains spread across the market rather than concentrated in a handful of large-cap tokens. However, if that breadth continues, the rally's price action will likely become more volatile should capital begin flowing away from smaller-cap tokens.
Exchange deposits raise selling-pressure risk
The rise in altcoin breadth is now colliding with a surge in exchange trading volume, a potential tipping point for the rally. On September 25, exchanges recorded about 70,000 altcoin deposits, the largest count since October 17, 2025.
Much of the flow came from Binance, while Coinbase, Bybit, and OKX added further inflows. Depositing tokens onto exchanges lifts trading activity, but it also adds to the supply of coins available for sale if the rally reverses or buying slows.
Continued growth in deposit volume may therefore create greater volatility for altcoins, as rising supply at higher price levels could outpace fresh demand.
Stablecoin supply signals limited fresh capital
Whether altcoins can sustain the rally now hinges on real liquidity. Stablecoin supply remains near $305 billion, pointing to limited new capital entering the market.
Rising prices can attract leverage even without new spot demand. If open interest grows faster than spot activity, traders become more dependent on borrowed exposure to keep the rally going, a structure that can magnify selling once prices reverse, especially after exchange deposits recently reached multi-month highs.
Stronger spot volume with contained funding would signal healthier demand behind the rally. Until then, the rally stays vulnerable to sharper volatility if positioning unwinds.
