Bitcoin’s October was marked by a significant rebound in volatility while still reflecting on its past performance. Of the 13 trading days, 10 saw gains, with an average increase of about 12.73%. Still, throughout the market there was a noticeable lack of momentum and a decline in ETF inflows that dampened activity.
Supply of wallets decreased, yet buying pressure for stable‑coin linked ETFs (such as USDT) weakened. According to large investors, when $1 million wallets were transferred onto Binance after May, the inflow fell by roughly $14 billion; however, since September it has recovered about $4 billion, leaving total supply still around $270 billion.
In particular, Bitcoin’s net ETF inflow peaked at $61 billion in October 2025 and then dropped sharply, with trading volume falling accordingly. On September 21, the daily net inflow was roughly $198.95 million; from September 28 to October 1, the four trades totaled about $512.5 million—much lower than the previous week’s $239 billion.
This flow is linked to geopolitical risks that have unsettled Bitcoin prices. For example, after a rise to $87 000, news of an attack on the U.S. led to a sharp decline in momentum. Because Bitcoin trades 24 hours a day, it can react swiftly to political news, yet volatility remains a risk.
Also, the potential for a shortfall in the market is highlighted by a pending debt‑recovery issue that could be resolved by month’s end. The current balance of 34 387.51 BTC still holds about $2.88 billion. If the debt recovery deadline falls on October 31, Bitcoin may not enter the market afterward; conversely, if the holder pays, some volume may flow out.
Thus, whether October’s political volatility repeats is uncertain. Bitcoin fell 3.69% in October 2025—the first month‑low since 2018—and this year remains unpredictable for that reason. Future stable‑coin supply and ETF inflows will likely be key indicators of new entrants.
