The Bitcoin spot ETF in the US mainland achieved its largest single-week trading volume in history in the last week of 2025, benefiting from the rise in Bitcoin prices that attracted a large inflow of funds. Last week, the asset value of these funds changed by up to $25 billion, surpassing any week since December 30 of last year, during which the net inflow reached $2.75 billion, the second highest since the beginning of the year. BlackRock's IBIT fund has seen no significant outflows for 30 consecutive days, with a holding ratio of 3.3% of the total Bitcoin supply, and a net value exceeding $71 billion. The ETH ETF also recorded fund inflows, but saw a slight decrease compared to the previous week. The BTC price remained stable after a slight drop last Friday, currently trading at $108,900.
