Capital inflows into digital assets dropped sharply last week, cutting $9 billion from Bitcoin and Ethereum’s cumulative accumulation. Analyst Ali (Ali on X) noted the decline, highlighting a shift after months of steady inflows that supported Bitcoin’s rally toward $120,000 in July. Aggregate Market Realized Value Net Position Change data showed slowing momentum while Bitcoin remains above $110,000.
How is Bitcoin price action reflecting the slowdown in inflows?
Bitcoin price momentum has moderated since July’s highs. The chart shows BTC rising from about $77,000 in March 2025 to a peak above $120,000 by late July, then settling between $110,000 and $116,000 in early September. Reduced accumulation suggests more cautious positioning, but ETF support limits downside pressure.

This stability comes amid a shift in stablecoin and liquidity positions. Stablecoin balances moved from approximately $12.5 billion on September 5 to $11.07 billion by September 12, signaling a modest return of liquidity and more cautious trader positioning. Combined, the data suggest lower on-chain accumulation but persistent liquidity from ETFs and rotating capital into altcoins.
Why are altcoins strengthening while inflows cool?
Altcoins have seen rotation as traders and institutions seek higher prospective returns. The Altcoin Index rose to 84/100 (data: CryptoRank), reflecting broader participation. Total crypto market capitalization sits at $4.25 trillion, and daily liquidations peaked near $360 million, indicating episodic volatility alongside increased altcoin demand ahead of the Federal Reserve decision on September 17.
