Bitcoin Tops ₺3.9 Million as Turkish Lira Slides to Record Low

US-listed Bitcoin and Ethereum ETFs recorded their highest level of inflows in a year. According to data from Farside UK, Ethereum ETFs logged about $270 million in inflows on Monday, while Bitcoin ETFs saw $999 million in net inflows, bringing combined single-day inflows for the two assets to nearly $1.3 billion. The Bitcoin inflow was the largest single day since about $835 million was recorded on October 6, 2025, and Ethereum also hit its highest level since $420 million on October 7, 2025. Eric Balchunas, chief ETF analyst at Bloomberg, said much of the reported inflows may stem from Friday buy orders and expressed the view that further inflows will appear in the coming days. Bitcoin ETFs hold a total of 1.4 million BTC, equivalent to about 6.97% of the circulating supply as of September 22. Meanwhile, Bitcoin's one-year active supply rate has fallen to about 36.7%, its lowest level since April 2025, suggesting long-term holders are reluctant to sell even during the rally.

Spot Bitcoin exchange-traded funds attracted nearly $1 billion U.S. of capital on Sept. 21 as the rally in cryptocurrencies strengthens. About a dozen U.S. Bitcoin ETFs registered a combined net inflow of $998.95 million U.S., the largest one-day intake since Oct. 6, 2025, when BTC hit a record high of $126,000 U.S. The inflow was the ninth-largest one-day total since the ETFs began trading on Jan. 11, 2024, according to data from SoSoValue. The Sept. 21 inflow has taken the month-to-date tally to $1.31 billion U.S. during September, building on August's $3.52 billion U.S. capital inflow to Bitcoin ETFs. The renewed institutional interest comes as Bitcoin's price has surged 44% over the past month to trade at $86,000 U.S. on Sept. 22, though owing to big redemptions earlier in the year, spot Bitcoin ETFs remain down $450 million U.S. in 2026.
